Comparative Study
F-18 FDG PET-CT in patients with recurrent glioma: comparison with contrast enhanced MRI.
The purpose of the study was to compare the efficacies of FDG PET-CT and contrast enhanced MRI in detection of recurrent gliomas. ⋯ FDG PET-CT is a highly specific modality for detecting recurrence in patients with gliomas and can effectively exclude post therapy changes.

To demonstrate radiographical characteristics of the relationship between distal spiral tibial shaft fractures and associated occult posterior malleolar fractures (PMF) that confirmed by CT and MRI. ⋯ It is important to understand the nature of the association between distal spiral tibial shaft fractures and occult posterior malleolar fractures for optimal stabilization of the fracture and for appropriate rehabilitation. The "communication line" is a useful diagnostic clue for early recognition the occult PMF and alerts a closer evaluation of the lateral view and further CT examination.

To assess role of contrast-enhanced ultrasound (CEUS) in decision support for diagnosis and treatment of hepatic artery thrombosis (HAT) after liver transplantation. ⋯ Our study demonstrates the important role of CEUS in decision support for diagnosis and treatment of HAT after liver transplantation. When HAT is suspected by Doppler ultrasound, CEUS shall immediately be performed to elucidate its nature. A negative CEUS finding shall avoid invasive angiography. Such as, CEUS may alter the clinical workflow on HAT detection after liver transplantation.

The aim of the present study was to evaluate the metallic artifacts in MRI of the orthopedic patients after removal of metallic implants. ⋯ Susceptibility of metallic artifacts is a frequent phenomenon in MRI of patients upon removal of metallic orthopedic implants.

We aimed to assess the contrast enhancement patterns of the retrodiscal tissue with dynamic contrast-enhanced MR imaging (DCE-MRI) with respect to different temporomandibular joint disc pathologies. Additionally, we questioned the relationship between the temporomandibular joint (TMJ) pain and the contrast enhancement pattern of the retrodiscal tissue regardless of the TMJ disc position. ⋯ The contrast enhancement patterns in the retrodiscal tissues of the painful joints showed significant differences in comparison with the painless joints. This result supports the hypothesis defending that inflammation and increased vascularity are responsible from the TMJ pain. Besides, the measurements from the retrodiscal tissues of the joints with partial displacement show significant difference between the signals of the displaced and non-displaced parts of the joints. Dynamic contrast-enhanced imaging revealed that different disc malpositions create different contrast enhancement patterns. On this basis, it is assessed that the types of the disc malpositions, which are believed to be acquired pathologies, are correlated with the retrodiscal inflammation degrees.
