Comparative Study
Comparison of multi-echo and single-echo gradient-recalled echo sequences for SPIO-enhanced liver MRI at 3 T.
To assess the utility of a T2*-weighted, multi-echo data imaging combination sequenced on superparamagnetic iron oxide (SPIO)-enhanced liver magnetic resonance imaging (MRI) using a 3 T system. ⋯ At 3 T, the T2*-weighted, multi-echo data image combination sequence performs comparably to the T2*-weighted, single-echo GRE sequence for SPIO-enhanced MRI with good overall image quality and a decrease in undesired artefacts.

To evaluate the benefits and logistical safety of computed tomography (CT) imaging in patients undergoing extracorporeal membrane oxygenation (ECMO) therapy in a single institution. ⋯ With an experienced team, CT imaging of patients on ECMO can be performed safely. CT provides valuable information for subsequent management of patients undergoing ECMO therapy.

Ketamine is a short-acting dissociative anaesthetic whose hallucinogenic side effects have led to an increase in its illicit use amongst club and party goers. There is a general misconception amongst users that it is a safe drug with few long term side effects, however ketamine abuse is associated with severe urinary tract dysfunction. Presenting symptoms include urinary frequency, nocturia, dysuria, haematuria and incontinence. ⋯ This case series illustrates the harmful effects of ketamine on the urinary tract and the associated radiological findings. Delayed diagnosis can result in irreversible renal tract damage requiring surgical intervention. It is important that radiologists are aware of this emerging clinical entity as early diagnosis and treatment are essential for successful management.

The present review systematically describes common fractures of the phalanges with reference to the anatomy and the pertinent radiological classifications; in particular, the role of radiology in indicating prognosis, guiding treatment, and revealing subtle injuries, which may cause permanent loss of function.

Sarcoidosis is a multisystem granulomatous disorder of unknown aetiology. The diagnosis is suggested on the basis of wide ranging clinical and radiological manifestations, and is supported by the histological demonstration of non-caseating granulomas in affected tissues. This review highlights the multisystem radiological features of the disease across a variety of imaging methods including multidetector computed tomography (CT), magnetic resonance imaging (MRI) as well as functional radionuclide techniques, particularly 2-[(18)F]-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography/computed tomography (PET/CT). It is important for the radiologist to be aware of the varied radiological manifestations of sarcoidosis in order to recognize and suggest the diagnosis in the appropriate clinical setting.
