Endoscopic and endobronchial ultrasound are complementary techniques. When combined, they allow for nearly complete mediastinal staging in lung cancer. Each technique has inherent strengths and weaknesses, but when used simultaneously they become far more powerful, to the extent that mediastinoscopy -a more expensive and invasive procedure- is expected to decline in use as the application of en...

The analogical description of a shape may be helpful in better understanding of anatomical structures during imaging. Seagull is a popular name for a seabird with a heavy body and two long wings. The “seagull sign ”has been used in cardiology for evaluation of the mitral valve and in orthopedics for erosive osteoarthritis.[1-3] On a plain X-ray abdomen, a triradiate collection of a dark shadow ...

2007〉 Recent developments in ultrasound (US) data processing have made it possible to develop new software. The latest generation of US workstations incorporate a central computer allowing very precise processing of the US image. This has made possible the reconstruction of images like three-dimensional US, second harmonic imaging for detecting contrast agents following intravenous injection, a...

Endoscopic ultrasound (EUS) is now firmly established as one of the essential tools for diagnosis in most gastrointestinal MDTs across the UK. However, the ability to provide therapy with EUS has resulted in a significant impact on the management of the patients. These include drainage of peripancreatic collections, EUS-guided endoscopic retrograde cholangiopancreatogram, EUS-guided coeliac ple...

Advancements in endoscopic technol­ ogy and techniques have increased our ability to characterize the etiology of pancreatic cysts. Endoscopic ultrasound (EUS), a relatively new technology, uses an ultrasound probe at the tip of an endoscope to provide high-quality, detailed images of structures in and around the gastrointestinal tract. During the procedure, an echoendo­ scope is advanced into ...

An esophageal hamartoma is a rare, benign germ-cell condition. Most hamartomas are intraluminal tumors located in the upper third of the esophagus. We herein report an unusual case of a pedunculated hamartoma that involved the lower third of the esophagus that was diagnosed incidentally during investigations for epigastric pain. The features noted on endoscopy, endoscopic ultrasound/Doppler end...

The therapeutic ability of endoscopic ultrasound has expanded, especially in assisting with radiation planning for image guided radiation techniques such as stereotactic body radiation therapy. Endoscopic ultrasound enables precise placement of fiducial markers into pancreatic cancers to accurately delineate the position of the target lesion as it moves with respiration. The authors summarize t...

Percutaneous image-guided biopsies of pancreatic malignancies may prove challenging and nondiagnostic due to a variety of anatomic considerations. For patients with complex post-surgical anatomy, such as a Roux-en-Y gastric bypass, diagnosis via endoscopic ultrasound with fine-needle aspiration may not be possible because of an inability to reach the proximal duodenum. This report describes the...

Pancreatic tuberculosis is a rare disease. It can be easily confused with malignancy or pancreatitis on imaging. This could result in unnecessary surgery. As this is a treatable disease it is imperative to diagnose this condition pre-operatively. We report three cases of pancreatic tuberculosis that were diagnosed by endoscopic ultrasound. In conclusion, endoscopic ultrasound is the diagnostic ...
