Hemorrhagic and non-hemorrhagic causes of signal loss on susceptibility-weighted imaging
This article will review the various hemorrhagic and non-hemorrhagic causes of low signal on SWI. There will be a focus on the distribution patterns of low signal on SWI in pathologies such as diffuse axonal injury, cerebral amyloid angiopathy, and cerebral fat embolism. It is important to recognize these patterns of susceptibility, as the radiologist may be the first to give an accurate diagnosis and therefore, directly impact clinical management.

BradleyAbstractEye lenses lie within the radiation field during computed tomography (CT) procedures of the brain. Therefore, patients are at risk of forming eye lens opacity when exposures exceed the threshold for such onset. The purpose of this study was to estimate the eye lens equivalent and radiation effective doses during CT procedures of the brain, facial bones, and paranasal sinuses.

Diagnostic Yield of Computed Tomography-Guided Transthoracic Lung Biopsy in Diffuse Lung Diseases
Conclusions: CT-TLB proved to be accurate and safe for the diagnosis of DLD. The overall diagnostic yield of the procedure was 66.3%. Given its low complication rates, CT-TLB can be an option in patients whose respiratory function is seriously impaired and in those with substantial comorbidities, where more invasive procedures cannot be performed for reasons of safety.Respiration (Source: Respiration)

Identification of probable telangiectatic osteosarcoma from a dog skull from multicultural settlement Polwica-Skrzypnik in Lower Silesia, Poland
This report presents canid cranial skeletal pathology from an excavation associated with the Przeworsk culture (III c. BC – V c. AD). The dog skull, an intentional inhumation, was dated to the Roman influence and the Migration period (I – V c. AD. The dog was a relatively large animal with a shoulder height calculated as approximately 60 cm. Massive bone changes localized on the facial surface of the left maxilla required a multistage diagnostic protocol. In addition to traditional macroscopic and morphometric evaluation, we used modern diagnostic imaging techniques such as digital radiography, computed ...

Pilomatrixoma: A Comprehensive Review of the Literature
Conclusion: Pilomatrixomas are thought to arise from mutation in the Wnt pathway and has been linked to several genetic conditions. It is commonly misdiagnosed preoperatively; however, with better awareness of the lesion, it can be appropriately treated while avoiding unnecessary diagnostic tests. Complete surgical excision with clear margins is almost always curative. (Source: The American Journal of Dermatopathology)

Surgical Treatment of Posterior Malleolus Fractures and Posterior Fixation
Posterior malleolar fractures (PMFs) have been demonstrated to result in poorer outcomes than other types of ankle fractures with a higher incidence of posttraumatic arthritis. Accordingly, there has been a recent surge in interest in reduction and fixation of PMFs. Operative criteria for PMFs have been based on size, step-off, ankle joint instability, and syndesmotic injury, though universally accepted criteria have yet to be defined. Anatomically, the posterior malleolus is important as an insertion point of the posterior inferior tibiofibular ligament and thereby may play a role in syndesmotic stability. However, the im...

The posterior pharyngeal wall thickness is associated with OSAHS in patients with acromegaly and correlates with IGF-1 levels
ConclusionsOSAHS is a common complication in patients with untreated acromegaly, and advanced age is a risk factor. Posterior pharyngeal soft tissue thickening and soft palate hypertrophy are structural changes underlying OSAHS development in patients with acromegaly. Higher IGF-1 levels predict an increase in the posterior pharyngeal soft tissue thickness in patients with acromegaly. (Source: Endocrine)

However, few contemporary studies have evaluated the prognostic value of three-dimensional (3D)-CTA for patients with acute coronary artery disease.
