Feasibility Study of 3-T DWI of the Prostate: Readout-Segmented Versus Single-Shot Echo-Planar Imaging.
The purpose of this prospective study was to assess the clinical utility of generalized autocalibrating partial parallel acquisition (GRAPPA)-accelerated readout-segmented echo-planar imaging (rs-EPI) DWI and compare it with standard single-shot EPI ( ss-EPI) DWI in visualization of the prostate during 3-T MRI. ⋯ The technique of rs-EPI DWI combined with GRAPPA enables robust prostate imaging with high image quality and may provide great benefit in routine clinical practice.

Is Biopsying the Paravertebral Soft Tissue as Effective as Biopsying the Disk or Vertebral Endplate? 10-Year Retrospective Review of CT-Guided Biopsy of Diskitis-Osteomyelitis.
The purpose of this study was to determine whether there is a difference in biopsying bone (endplate), disk, or paravertebral soft tissue to culture the pathogenic organism causing diskitis-osteomyelitis. ⋯ Paravertebral soft-tissue changes, when present, may be considered a viable target for biopsy in cases of diskitis-osteomyelitis, even in the absence of a paravertebral abscess.

Chemoembolization of recurrent hepatoma after curative resection: prognostic factors.
The long-term prognosis after hepatic resection for the treatment of hepatocellular carcinoma (HCC) has been disappointing because of the high recurrence rates in the remnant liver, which constitutes the major cause of death. The purpose of this study was to identify the prognostic factors for overall survival after transarterial chemoembolization (TACE) in recurrent HCC after the initial curative surgical resection. ⋯ TACE appears to be an effective treatment of patients who experienced a recurrence after curative HCC resection. An initial solitary HCC, a solitary recurrence, and recurrent tumor mass 5 cm or smaller are statistically significant independent prognostic factors for survival.

High Spatiotemporal Resolution Dynamic Contrast-Enhanced MR Enterography in Crohn Disease Terminal Ileitis Using Continuous Golden-Angle Radial Sampling, Compressed Sensing, and Parallel Imaging.
The purpose of this article was to assess the feasibility of golden-angle radial acquisition with compress sensing reconstruction (Golden-angle RAdial Sparse Parallel [GRASP]) for acquiring high temporal resolution data for pharmacokinetic modeling while maintaining high image quality in patients with Crohn disease terminal ileitis. ⋯ High temporal resolution data for pharmacokinetic modeling and high spatial resolution data for morphologic image analysis can be achieved in the same acquisition using GRASP.

ReviewImaging of acute and emergent genitourinary conditions: what the radiologist needs to know.
Acute and emergent genitourinary conditions require accurate and rapid diagnosis to minimize patient morbidity and mortality. ⋯ Radiologists' familiarity with the various conditions of the urinary system and of the male and female reproductive organs is important given the widespread use of imaging for the diagnosis of common clinical entities presenting to the emergency department.
