At liver magnetic resonance (MR) imaging in 38 patients, a breath-hold T2-weighted fast spin-echo (SE) pulse sequence optimized with fast recovery was compared with a conventional respiratory-triggered fast SE sequence and a breath-hold single-shot fast SE sequence. Mean signal-to-noise ratios for liver and contrast-to-noise ratios for hepatic lesions were higher with the breath-hold fast-recovery fast SE sequence than with the respiratory-triggered fast SE sequence (P <.05). ⋯ The ability to determine lesion size and the overall image quality was best with the breath-hold fast-recovery sequence (P <.05). These results may justify use of the breath-hold fast-recovery fast SE pulse sequence for first-line T2-weighted MR imaging of the liver.

Randomized Controlled Trial Comparative Study Clinical Trial
Suspected appendicitis in children: US and CT--a prospective randomized study.
To evaluate the accuracy of ultrasonography (US) and of abdominal computed tomography (CT) performed in addition to US in the diagnosis of childhood appendicitis. ⋯ US is valuable in the diagnosis of appendicitis in children. In inconclusive cases, performing additional abdominal CT can improve diagnostic accuracy and thereby decrease the negative appendectomy rate without an increase in the perforation rate.

To evaluate superselective embolization therapy for the management of arterial damage in patients with severe renal trauma. ⋯ Superselective embolization may be used for effective, minimally invasive control of active renovascular bleeding.

To investigate whether proton magnetic resonance (MR) spectroscopy is a useful complement to MR imaging in patients with degenerative ataxia. ⋯ MR spectroscopy is a useful complement to MR imaging in patients with degenerative ataxia.
