Ultrasonic Detection of Choledocholithiasis

EUS vs MRCP for detection of choledocholithiasis.

BACKGROUND Numerous published studies have shown the high diagnostic performance of both EUS and MRCP compared with ERCP for the detection of choledocholithiasis. DESIGN We undertook a systematic review of all published randomized, prospective trials that compared EUS with MRCP with the primary aim being to compare the overall diagnostic accuracy for the detection of choledocholithiasis in pa...

The Value of Magnetic Resonance Cholangio-Pancreatography (MRCP) in the Detection of Choledocholithiasis Key words: Choledocholithiasis, MRCP, ERCP

IntrOductIOn Cholelithiasis is the most common biliary pathology. The incidence of choledocholithiasis in patients with cholelithiasis varies between 5 to 15 percent, out of which 5% are asymptomatic [1]. Although common bile duct (CBD) stones may be silent, the development of complications such as cholangitis and acute pancreatitis is associated with major morbidity and mortality. Therefore, t...

Ultrasonic detection and imaging of

Brachytherapy to treat prostate cancer uses transrectal ultrasound to guide transperitoneal needle implantation of titanium-shelled radioactive seeds. The standard external dimensions of all seeds used for prostate brachytherapy is 4.5 mm in length and 0.85 mm in diameter. Gland deformation and needle deflection during implantation allow seed-placement errors that cause suboptimal dosimetry. Co...
