Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a minimally invasive procedure for acquiring biopsies in gastric regions that are hard to reach otherwise (e.g. the pancreas). Endoscopic ultrasound EUS-FNA of cystic lesions, followed by liquid cell analysis, has been used as a diagnostic tool for differentiating benign ...
Endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy (insertion of a probe into a hollow organ) is combined with ultrasound to obtain images of the internal organs in the chest, abdomen and colon. It can be used to visualize the walls of these organs, or to look at adjacent structures.
The role of endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) in the diagnosis of AIP is not well described, and EUS findings have been described in only a small number of patients. In one study, EUS revealed a diffusely swollen and hypoechoic pancreas in 8 of the 14 (57%) patients, and a solitary, focal, irregular ...
The diagnosis of pancreatic MCN is typically achieved with imaging. If the results of imaging (CT/MRI) are unclear, then endoscopic ultrasound with fine needle aspiration (EUS-FNA) of the cyst may be necessary. [1] Cyst fluid analysis may help distinguish potentially premalignant mucinous cysts (MCNs and IPMNs), from benign non-mucinous cysts. [1]
The procedure involves taking a core of trabecular bone using a trephine, and then aspirating material. Breast: Breast biopsy is often performed to assess or diagnose breast cancer, and can be performed by various methods such as fine needle aspirate (FNA), core needle biopsy (CNB), or surgical removal.

The double duct sign is a radiological finding characterized by the simultaneous dilation of the common bile duct and the main pancreatic duct.This sign is significant because it often indicates an obstruction in the distal bile duct and pancreatic duct, frequently caused by serious underlying pathologies such as pancreatic carcinoma or periampullary tumors.

Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. It is primarily performed by highly skilled and specialty trained gastroenterologists.
The most common and effective method of diagnosing a pancreatic pseudocyst is with a CT scan. A pseudocyst generally appears as a fluid-filled mass. In some instances, other methods must be used to distinguish between a normal cyst and a pseudocyst. [3] This is usually accomplished with endoscopic ultrasound or with fine needle aspiration. [2]
