Case Reports
Sonoelastography for the evaluation of an axillary schwannoma in a case of quadrilateral space syndrome.
Entrapment axillary neuropathy at the quadrilateral space, also known as quadrilateral space syndrome (QSS), is a rare cause of posterior shoulder pain. We present a case of an axillary schwannoma causing QSS evaluated by both conventional ultrasound and sonoelastography. The application of sonoelastography is useful in elaborating the elastic feature of a soft tissue tumor, which provides additional information to conventional ultrasound regarding its growth pattern, and can help the differential diagnosis and guide the management.

The purpose of our study was to investigate the impact of clinical risk classification on optimization of the rationale of CT scanning in children with mild blunt head trauma. Exposed effective radiation dose values of CT scanning were also evaluated. ⋯ The pediatric victims of mild head trauma patients within high risk group and those with vomiting, suspected skull fracture and loss of consciousness should undergo head CT scanning. The manufacturer settings on the CT scanners for children should be revised to alleviate untoward radiation exposure.

Comparative Study
Clinical application of 3D VIBECAIPI-DIXON for non-enhanced imaging of the pancreas compared to a standard 2D fat-saturated FLASH.
To compare a fast 3D VIBE sequence with Dixon fat saturation and CAIPIRINHA acceleration techniques (3D VIBE(CAIPI-DIXON)) to a standard 2D FLASH sequence with spectral fat saturation and conventional GRAPPA acceleration technique (2D Flash(GRAPPA-fs)) for non-enhanced imaging of the pancreas. ⋯ 3D VIBE(CAIPI-DIXON) enables robust pancreatic imaging with a shorter time and improved fat suppression relative to conventional 2D Flash(GRAPPA-fs). At an acquisition time of 12 seconds, 3D VIBE(CAIPI-DIXON) can be obtained in considerably less time than standard fat-saturated VIBE sequences.

Delayed splenic rupture following conservative management of splenic injury is an extremely rare complication. We report a case of an adult patient who presented with delayed splenic rupture necessitating splenectomy, 2 months following blunt abdominal trauma. Imaging at the initial presentation demonstrated only minimal splenic contusion and the patient was discharge following 24 hours of observation.

To investigate diagnostic accuracy for acute appendicitis at computed tomography (CT) as a performance metric for radiologists specialized in abdominal imaging. ⋯ Diagnostic accuracy for acute appendicitis at CT may be an impractical performance metric for radiologists specialized in abdominal imaging.
