Prediction of cerebral hyperperfusion syndrome after carotid stenting: a cerebral perfusion computed tomography study.
The objective of this study was to evaluate the role of cerebral perfusion computed tomography (CT) in predicting cerebral hyperperfusion syndrome (CHS) after carotid stenting. ⋯ Our findings suggest that patients with a prolonged dMTT of more than 3 seconds should be closely monitored for evidence of hyperperfusion after undergoing carotid stenting.

Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography imaging in pyogenic and tuberculous spondylitis: preliminary study.
The purpose of this study was to compare the effectiveness of positron emission tomography (PET)/computed tomography (CT) in distinguishing between tuberculous and pyogenic spondylitis with that of magnetic resonance imaging (MRI). ⋯ The maximum SUVs of early-phase PET/CT may be complementary to MRI for differentiating pyogenic and tuberculous spondylitis and reflecting the activity of infectious spondylitis.

Case ReportsSimultaneous occurrence of partial anomalous pulmonary venous return and major bronchial anomaly: computed tomography findings in 5 adult patients.
The objective of this study was to describe the computed tomography (CT) findings of 5 adult patients with a combination of partial anomalous pulmonary venous return (PAPVR) and major bronchial anomaly. ⋯ A combination of right PAPVR draining to the superior vena cava or azygos arch and right TB is most common. The possibility that the PAPVR and a major bronchial anomaly might coexist in 1 patient should be considered whenever either of them is encountered on CT.

Magnetic resonance imaging of stress injury of the cuneiform bones in patients with plantar fasciitis.
The authors reported the magnetic resonance (MR) appearance of stress fractures of the cuneiform bones in patients with plantar fasciitis and performed a review of the literature on stress fractures associated with plantar fasciitis. ⋯ Plantar fascia injury, changes in gait, large body habitus, and excessive or new onset of exercise regimens are all potential causes of cuneiform stress fractures. Although the incidence of cuneiform stress fractures is extremely rare, they may occur in patients with plantar fasciitis.

High-resolution magnetic resonance imaging of triangular fibrocartilage complex lesions in acute wrist trauma: image quality at different field strengths.
The purposes of this study were to assess the diagnostic capacity of a new high-resolution imaging protocol for the wrist and triangular fibrocartilage complex (TFCC) lesions at 3.0 T and to compare it with our established 1.5-T protocol. ⋯ Depiction of anatomy and pathology of the TFCC benefits significantly from 3.0-T imaging when higher signal-to-noise ratio is invested into improved spatial resolution. Especially small lesions of the disk were detected only or better at 3.0 T.
