Pancreas Ultrasound Anatomy Flashcard

Front

What is the normal size of the pancreatic duct in comparison to the ultrasound assessment?

Back

Less than 2.5 mm

Answer explanation

The normal size of the pancreatic duct is typically less than 2.5 mm. This measurement is important for assessing pancreatic health, making 'Less than 2.5 mm' the correct choice.

Front

What imaging technique shows complete fat suppression in the pancreas?

Back

MRI T1 fat suppressed images

Answer explanation

MRI T1 fat suppressed images effectively eliminate fat signals, providing clear visualization of pancreatic structures. Other techniques like CT, X-ray, and ultrasound do not achieve complete fat suppression.

Front

What condition is characterized by heterogenous pancreatic parenchyma and calcifications?

Back

Chronic calcifying pancreatitis

Answer explanation

Chronic calcifying pancreatitis is characterized by heterogeneous pancreatic parenchyma and calcifications, distinguishing it from acute pancreatitis, pancreatic adenocarcinoma, and autoimmune pancreatitis.

Front

What is a common limitation of ultrasound evaluation of the pancreas?

Back

Obese patients

Answer explanation

Obese patients present a common limitation for ultrasound evaluation of the pancreas due to increased body fat, which can hinder sound wave penetration and image clarity, making it difficult to visualize the pancreas effectively.

Front

What imaging technique improves discrimination between solid and cystic lesions?

Back

Tissue harmonic imaging

Answer explanation

Tissue harmonic imaging enhances the quality of ultrasound images, allowing better differentiation between solid and cystic lesions due to improved resolution and contrast, making it the preferred choice over other imaging techniques.

Front

What is the typical appearance of pancreatic adenocarcinoma on ultrasound?

Back

Hypoechoic with irregular contour

Answer explanation

Pancreatic adenocarcinoma typically appears hypoechoic with an irregular contour on ultrasound, distinguishing it from other lesions. This characteristic helps in identifying the malignancy during imaging.

Front

What technique allows for the display of the entire pancreas in a single image?

Back

Panoramic imaging

Answer explanation

Panoramic imaging is a technique that captures a wide view, allowing the entire pancreas to be displayed in a single image. This is essential for comprehensive assessment, unlike the other techniques listed.

Front

What is the significance of capsule thickness greater than 4.5 mm?

Back

Indicates autoimmune pancreatitis

Answer explanation

A capsule thickness greater than 4.5 mm is significant as it indicates autoimmune pancreatitis, a condition characterized by inflammation and fibrosis of the pancreas, distinguishing it from other pancreatic disorders.

Front

What is the purpose of sono-portation in pancreatic treatment?

Back

To combine chemotherapy with ultrasound

Answer explanation

Sono-portation is used to combine chemotherapy with ultrasound, enhancing the delivery of drugs directly to pancreatic tumors while minimizing side effects. This targeted approach improves treatment efficacy.

Front

What is a common feature of lipomatous pseudohypertrophy in ultrasound imaging?

Back

Fatty attenuation

Answer explanation

Fatty attenuation is a common feature of lipomatous pseudohypertrophy in ultrasound imaging, indicating the presence of fat, which typically appears as areas of decreased echogenicity compared to surrounding tissues.
