OBJECTIVE: In previous studies, post-stroke depression (PSD) was found to be related to stroke characteristics as well as social and psychological factors. This study identified altered functional connectivity (FC) in patients with PSD at the subacute phase in three brain networks: default mood network (DMN), cognitive control network (CCN), and affective network (AN). The correlation between FC and the severity of PSD was investigated. MATERIALS AND METHODS: Resting-state functional magnetic resonance image (rs-fMRI) was performed on 26 PSD patients (6 females), 24 stroke patients without depression (5 females), and 24 age-matched normal controls (6 females) all aged 40-75 years...

Behcet's disease is an autoimmune disease most commonly seen in the Middle East. Although primarily known with painful oral and genital ulcers, it can lead to vasculitis. Therefore, several associated complications such as thrombotic syndromes, aneurysmal arterial disease may arise. In many cases, it might be difficult to make the diagnosis purely based on clinical grounds; however, imaging plays an important role for both diagnosis and assessment of the disease's complications. We provide a comprehensive review of the most notable imaging findings of Behcet's disease...

BACKGROUND: Osteoporosis is a common but underdiagnosed and undertreated disease causing severe morbidity and economic burden. The gold standard for detection of osteoporosis is DXA (dual energy x-ray absorptiometry), which is a dedicated examination for osteoporosis. Dual energy CT (DECT) examinations are increasingly used in daily routine for a wide variety of diagnoses. In the present study, we wanted to examine whether vBMD (volume bone mass density) could be evaluated as a side product in non-contrast as well as contrast phases as well as to evaluate a correction model taking known shortcomings for DXA into account...

As our understanding has expanded that relatively large fraction of incidentally discovered renal masses, especially in small size, are benign or indolent even if malignant, there is growing acceptance of more conservative management including active surveillance for small renal masses. As for advanced renal cell carcinomas (RCCs), nonsurgical and subtype specific treatment options such as immunotherapy and targeted therapy is developing. On these backgrounds, renal mass characterization including differentiation of benign from malignant tumors, RCC subtyping and prediction of RCC aggressiveness is receiving much attention and a variety of imaging techniques and analytic methods are being investigated...

Anterior cruciate ligament reconstruction is a commonly performed orthopaedic procedure which has increased in frequency over the past decade. There are a variety of fixation devices used to secure grafts within the femoral and tibial tunnels during the reconstruction procedure. An understanding of the expected appearance of the varied hardware utilized for reconstruction graft fixation, and their potential complications is important in the review of post-operative imaging. We describe the most common anterior cruciate ligament reconstruction fixation devices and illustrate their more frequently documented abnormalities...
