OBJECTIVE The purpose of this study was to evaluate an MR sequence using half-Fourier acquisition single-shot turbo spin-echo (HASTE) imaging in the assessment of ureteric obstruction. SUBJECTS AND METHODS We prospectively evaluated 111 kidneys in 56 consecutive patients with HASTE MR urography and compared that imaging technique with excretory urography.(More)
OBJECTIVE We performed this study to evaluate the usefulness of a new T2-weighted MR sequence using a half-Fourier acquisition single-shot turbo spin-echo (HASTE) technique in the diagnosis of bile duct stones. SUBJECTS AND METHODS We prospectively evaluated 23 patients with suspected bile duct calculi using HASTE MR cholangiography and compared that(More)
OBJECTIVE Our aim was to determine whether fast MR imaging using the half-Fourier acquisition single-shot turbo spin-echo (HASTE) MR sequence is accurate for diagnosis of small-bowel obstruction. MATERIALS AND METHODS Forty-three nonconsecutive patients with suspected small-bowel obstruction were evaluated with HASTE MR imaging during a 12-month period.(More)
We report three cases of emphysematous pyelonephritis, all of them associated with perinephric emphysema, and one case of emphysematous pyelitis to demonstrate the value of computerized tomography (CT) in both diagnosis and patient management. The differentiation between air in the collecting system (emphysematous pyelitis), air within the parenchyma(More)
The G protein beta5 subunit differs substantially in amino acid sequence from the other known beta subunits suggesting that beta gamma dimers containing this protein may play specialized roles in cell signaling. To examine the functional properties of the beta5 subunit, recombinant beta5 gamma2 dimers were purified from baculovirus-infected Sf9 insect cells(More)
PURPOSE Our goal was to evaluate biliary obstruction using a T2-weighted, turbo, SE MR sequence with half-Fourier acquisition (HASTE). METHOD A prospective evaluation of 21 consecutive patients with clinical evidence of obstructive jaundice was carried out comparing HASTE MR cholangiography (MRC) to endoscopic retrograde cholangiopancreatography and(More)
A case of renal cell carcinoma in a patient with situs inversus totalis is reported. Only 8 cases of malignant neoplasms have been reported in situs inversus totalis, and our case represents the second case report of renal cell carcinoma in a patient with situs inversus totalis. The frequency of situs inversus totalis is between 1 in 8,000 and 1 in 20,000.(More)
OBJECTIVE Using a personal computer-based teleradiology system, we compared accuracy, confidence, and diagnostic ability in the interpretation of digitized radiographs to determine if teleradiology-imported studies convey sufficient information to make relevant clinical decisions involving urology. Variables of diagnostic accuracy, confidence, image(More)
PURPOSE Teleradiology systems are now being evaluated as a mechanism to provide rapid, accurate and cost-effective diagnostic radiographs to off-site physicians. Little data are available on the role and safety of teleradiology in urology. To address these issues a personal computer based system was developed to assess the diagnostic accuracy and ease of(More)
Urethral injuries are seen in association with fractures of the pelvic bones secondary to blunt abdominal trauma. A fistulous communication between the posterior urethra and the hip joint is a rare finding. A potentially serious complication of this fistulous communication is the development of a septic hip joint. Four such cases have been reported, and(More)
