Erectile dysfunction (ED) is a condition in which men have difficulty maintaining an erection. This condition has a significant impact on the quality of life and intimate relationships. While there are various diagnostic tools available to evaluate ED, penile Doppler ultrasound has emerged as a valuable technique for assessing vascularcauses of the condition.
What is Doppler ultrasound?
Doppler ultrasound is a non-invasive procedure that provides information about blood flow and helps diagnose various conditions related to the circulatory system.
In a basic Doppler ultrasound, the transducer is held against the skin and moved over the area of interest. The Doppler mode of the ultrasound machine detects the frequency shift in the reflected sound waves and generates color-coded images or waveforms to represent the velocity and direction of blood flow. This information helps in evaluating blood circulation in different areas of the body, detecting abnormalities, and monitoring the progress of certain conditions.
How does penile Doppler ultrasound for erectile dysfunction work?
Penile Doppler ultrasound evaluates the vascular dynamics of the blood flow within the arteries and veins of the penis. The accuracy of results is up to 95%. It helps to identify any underlying abnormalities that may be causing or contributing to erectile dysfunction. The procedure involves the use of a specialized ultrasound probe and a gel for optimal contact and sound wave transmission.
Penile Doppler ultrasound test price in Pakistan varies among different institutes. While many laboratories claim to perform this procedure, only a few provide reliable results, as this test is performed by highly trained radiologists.
Prior to the procedure, the doctor will educate you about the process and any necessary preparations. This may include refraining from caffeine or smoking, which can affect blood flow and the avoidance of medications that may interfere with the results.
You will be placed in a supine position with the penis exposed for the examination. The environment is relaxed and very comfortable to ensure accurate results. The radiologist then applies a water-based gel to the penile shaft and gently positions a high-frequency ultrasound probe over the penis. The probe emits sound waves that bounce off the tissues and blood vessels, creating real-time images on a monitor.
Initially, a baseline ultrasound scan of the penis is performed. This involves obtaining images of the penis in its flaccid state. It helps evaluate the anatomy of the penis and identify any structural abnormalities that may be contributing to ED.
After the baseline ultrasound, a drug is injected into the penis to induce an erection. The ultrasound machine is set to Doppler mode, which enables the detection of blood flow within the penile arteries and veins. The machine generates color-coded images, where red represents arterial flow (blood flow towards the probe) and blue represents venous flow (blood flow away from the probe).
The interpretation of the penile Doppler ultrasound includes the following parameters:
Peak Systolic Velocity (PSV): PSV measures the maximum speed of blood flow in the penile arteries. Lower PSV values may indicate arterial insufficiency, while higher values may suggest non-vascular causes of erectile dysfunction.
End Diastolic Velocity (EDV): EDV represents the minimum speed of blood flow during diastole. Elevated EDV values may indicate venous leakage, a common cause of erectile dysfunction.
Resistive Index (RI): RI is calculated by comparing the difference between systolic and diastolic velocities to the systolic velocity. A higher RI value indicates increased resistance to blood flow, potentially indicating arterial insufficiency.
Other Considerations: The examiner will also assess the presence of any arterial or venous plaques, anatomical abnormalities, or structural deformities that may contribute to erectile dysfunction.
Penile Doppler ultrasound provides valuable information for diagnosing the vascular component of erectile dysfunction. By evaluating the blood flow dynamics in real-time, clinicians can identify arterial insufficiency, venous leakage, or a combination of both. This information helps in developing an individualized treatment plan, which may include lifestyle modifications, medications, or surgical interventions such as penile revascularization or penile prosthesis placement.
It is important to note that penile Doppler ultrasound focuses primarily on vascular causes of erectile dysfunction and may not identify other potential contributing factors such as psychological or hormonal issues. Therefore, a comprehensive evaluation, including a detailed medical history and physical examination, should be conducted alongside penile Doppler ultrasound to provide a holistic understanding of the condition.

Fatty liver is a condition commonly observed in obese individuals. It is characterized by the accumulation of excess fat in liver cells. When a person is obese, their adipose tissue (fat tissue) releases fatty acids into the bloodstream at an increased rate. The liver take up these fatty acids and store them as triglycerides, leading to fat accumulation in liver cells.
Symptoms of fatty liver:
Patients with fatty liver may experience varying degrees of symptoms. Grade 1 fatty liver disease is typically asymptomatic, while others may present with:
Fatigue
Weakness
Weight loss or loss of appetite
Abdominal discomfort or pain in the upper right area
Enlarged liver (hepatomegaly)
Elevated liver enzymes in blood tests (asymptomatic fatty liver)
Causes:
The causes of fatty liver include
Obesity:
Excessive weight gain and obesity result in an increased accumulation of fat in the body, including the liver. When the body’s fat stores exceed the capacity of fat cells to store it, fat starts accumulating in other organs, such as the liver.
Alcohol consumption:
Excessive alcohol consumption leads to alcoholic fatty liver disease.
Non-alcoholic fatty liver disease (NAFLD):
This condition is unrelated to alcohol consumption and is associated with factors such as obesity, insulin resistance, diabetes, high blood pressure, high cholesterol, and metabolic syndrome.
Medications:
Certain medications like corticosteroids, tamoxifen, and methotrexate can contribute to this condition.
Rapid weight loss:
Losing weight too quickly can cause fat to accumulate in the liver.
Genetics:
Some genetic conditions, such as inherited liver diseases, can increase the risk of developing this disease.
Diagnosing fatty liver:
The diagnosis of fatty liver typically involves a combination of medical history, physical examination, blood tests, and imaging studies. A common diagnostic tool is a fatty liver ultrasound examination, which assesses the liver for excess fat accumulation by visualizing its texture and detecting changes in echogenicity (the ability to reflect ultrasound waves).
Treatment:
The treatment takes a holistic approach, starting with healthy lifestyle changes, including weight loss (if overweight), regular exercise, and a balanced diet.
A healthy diet plays a crucial role in managing and potentially reversing this condition. The primary goals of a fatty liver diet are promoting weight loss (if necessary), reducing fat accumulation in the liver, improving insulin sensitivity, and supporting overall liver health. Here are some pointers for planning your diet:
Opt for whole grains (e.g., whole wheat bread, brown rice, quinoa) instead of refined carbohydrates. These complex carbohydrates have a lower glycemic index and help regulate blood sugar levels.
Include plenty of fruits, vegetables, legumes, and whole grains to boost fiber intake, aiding digestion, promoting satiety, and potentially assisting with weight management.
Incorporate lean protein sources (e.g., skinless poultry, fish, tofu, beans, legumes) into your meals, as they are lower in fat and beneficial for liver health.
While it’s important to reduce overall fat intake, including healthy fats in your diet is equally crucial. Choose sources like olive oil, avocados, nuts, and seeds, providing essential fatty acids that positively impact liver health.
Foods to avoid with fatty liver are saturated and trans fats, high carbohydrates, refined foods, and fried or greasy meals.
Medications are prescribed in some cases to manage specific underlying conditions or improve liver health. However, there is currently no specific medication approved for the treatment of this disease.
For obese patients, surgery is sometimes recommended when other measures and medications are ineffective. The conventional surgical option for obesity are Gastric Sleeve and Bariatric bypass procedures, which comes with numerous complications and requires a prolonged recovery period. A new treatment for fatty liver disease is a minimally invasive approach called GAMMA-Block-BAE gamma block bariatric arterial embolization, pioneered by Dr. Imtiaz Ahmad and introduced for the first time in November 2017.
Dr Imtiaz is an expert interventional radiologist and an endovascular surgeon who works on the principles of minimally invasive treatment. This procedure was introduced by him for the very first time in Pakistan. It helps the patient to lose weight and ultimately the fatty liver gets treated.

Varicose veins can be a frustrating and uncomfortable condition, affecting millions of individuals worldwide. These enlarged, twisted veins not only cause aesthetic concerns but can also impact one’s mobility and endurance. Thankfully, advancements in medical science offer hope for affected individuals, providing the best treatment for varicose veins via a minimally invasive approach without further complications of anesthesia and surgery.
How Varicose Veins Affect Mobility and Endurance:
Varicose veins occur when the valves within the veins become weakened or damaged, causing blood to pool and veins to enlarge. They have a direct impact on mobility due to the discomfort they cause. Pain and swelling in the legs can make it challenging to engage in physical activities such as walking, jogging, or even standing for extended periods. This reduction in mobility not only affects one’s ability to perform daily tasks but also hampers overall fitness levels. Additionally, varicose veins can lead to muscle cramps, making it difficult to sustain physical activity and further limiting endurance.
Treatment of Varicose Veins:
The good news is that treating varicose veins can lead to a significant improvement in mobility and endurance. While many institutes across Pakistan offer conventional methods for the treatment of varicose veins, Dr. Imtiaz Ahmed is the first person to introduce advanced treatment options for varicose veins, utilizing the latest technology and advanced machinery.
Some of the advanced methods used by a varicose vein specialist are:
Machanochemical Endovenous Ablation Clariven:
This method combines mechanical and chemical means to treat varicose veins. The procedure involves inserting a special catheter into the affected vein. The catheter emits mechanical energy in the form of a rotating wire, which disrupts the endothelial lining of the vein. At the same time, a liquid sclerosant is infused into the vein, causing it to collapse and seal shut. The result is the occlusion of the varicose vein, and blood flow is redirected to healthy veins. This procedure takes hardly 15-20 minutes to complete, and the result is expected to be seen soon after.
VenaSeal:
During a VenaSeal procedure, an FDA-approved medical adhesive is injected into the affected vein using a small catheter. The adhesive is designed to seal the vein, preventing blood from flowing through it. Once the vein is closed off, blood is naturally rerouted to healthier veins, improving circulation and reducing the appearance and symptoms of varicose veins.The VenaSeal procedure is performed under local anesthesia on an outpatient basis. It does not require multiple needle sticks or the use of additional numbing solutions, resulting in a more comfortable experience for patients.
Sclerotherapy:
This method is preferred, particularly for smaller varicose veins and spider veins. The procedure involves injecting a sclerosant solution directly into the affected vein. The solution irritates the vein’s inner lining, causing it to swell, stick together, and eventually close off. This reroutes the blood flow to healthier veins.
Endovenous Laser Therapy:
This procedure involves inserting a thin laser fiber into the affected vein through a small incision. The fiber emits laser energy, which heats up the vein, causing it to close off. This thermal ablation process redirects blood flow to healthier veins. Endovenous laser therapy is performed under local anesthesia or light sedation on an outpatient basis.
Radiofrequency Ablation:
During this procedure, a thin catheter is inserted into the affected vein under ultrasound guidance. The catheter delivers radiofrequency energy to the vein wall, heating it and causing it to collapse. The heat generated by the radiofrequency energy seals the vein, redirecting blood flow to healthier veins. Radiofrequency ablation is performed under local anesthesia or light sedation on an outpatient basis.
By eliminating the underlying venous insufficiency, these treatments help reduce pain, swelling, and discomfort. As a result, individuals can experience a boost in mobility and regain the ability to engage in physical activities without limitations. Walking, running, and participating in sports become more comfortable and enjoyable, allowing individuals to lead a more active lifestyle.
It is estimated that up to 90-95% of patients can be successfully treated by minimally invasive procedures. The type of treatment varies for patients, depending on the extent of the disease and symptoms. The varicose vein doctor usually orders a duplex ultrasound before deciding the best treatment option for you.
