Imaging findings and treatment in coccydynia - update of the recent study findings.

Background: Coccydynia is one of the most overlooked symptoms in clinical practice. The diagnosis and radiologic findings of traumatic coccyx can be more easily detected unless it is delayed and postponed. For idiopathic coccydynia, which accounts for one third of cases, patients present with long-standing pain and multiple physician visits.

Virtual contrast enhancement for CT scans of abdomen and pelvis.

Contrast agents are commonly used to highlight blood vessels, organs, and other structures in magnetic resonance imaging (MRI) and computed tomography (CT) scans. However, these agents may cause allergic reactions or nephrotoxicity, limiting their use in patients with kidney dysfunctions. In this paper, we propose a generative adversarial network (GAN) based framework to automatically synthesize contrast-enhanced CTs directly from the non-contrast CTs in the abdomen and pelvis region.

American College of Rheumatology (ACR) Fibromyalgia criteria 1990 and ACR 2010 and for diagnosing patients with SpA; criteria from the European Spondyloarthropathy Study Group (ESSG), and Amor were applied.

Eliminating rib shadows in chest radiographic images providing diagnostic assistance.

A major difficulty with chest radiographic analysis is the invisibility of abnormalities caused by the superimposition of normal anatomical structures, such as ribs, over the main tissue to be examined. Suppressing the ribs with no information loss about the original tissue would therefore be helpful during manual identification or computer-aided detection of nodules on a chest radiographic image. In this study, we introduce a two-step algorithm for eliminating rib shadows in chest radiographic images.

Intraosseous angiolipoma of the frontal bone with a unique location: a clinical and pathological case illustration and review of the literature.

Postpartum sacral stress fracture: an unusual case of low-back and buttock pain.

Low-back and buttock pain is a common complaint during pregnancy and the postpartum period and is usually attributable to mechanical lesions of the pelvis. Sacral stress fractures are unusual but important causes that should be considered in differential diagnosis. To date, only eight postpartum sacral stress fractures have been reported in the literature.

Abnormal diffusion-weighted imaging findings in an adult patient with acute cerebellitis presenting with a normal magnetic resonance imaging.

Acute cerebellitis is an unusual central nervous system complication of infectious disease often due to viral etiology. Diagnosis is aided by neuroimaging studies, actually by magnetic resonance imaging in the first place, which shows increased signal intensity on T2-weighted images. However, conventional magnetic resonance imaging may be unrevealing in some of the cases, and additional workup such as single photon emission computed tomography and diffusion-weighted imaging may be required.
