To analyze intranodular signal intensity pattern of hypovascular high-risk borderline lesions of HCC that illustrate multi-step hepatocarcinogenesis within the nodule on Gd-EOB-DTPA-enhanced MRI. ⋯ In most of the hypovascular high-risk borderline lesions containing hypervascular foci within the nodule, the signal intensity was decreased in hypervascular foci as compared with hypovascular high-risk borderline lesions and the surrounding background liver parenchyma. This supports the concept of signal intensity decrease during the dedifferentiation process in multistep hepatocarcinogenesis. However, around 30% of the nodules did not follow this rule, and hypervascular foci showed hyperintensity relative to the hypovascular high-risk borderline lesions.

Review Meta Analysis
Accuracy and consequences of 3D-fluoroscopy in upper and lower extremity fracture treatment: a systematic review.
The aim of this systematic review was to compare the diagnostic accuracy, subjective image quality and clinical consequences of 3D-fluoroscopy with standard imaging modalities (2D-fluoroscopy, X-ray or CT) during reduction and fixation of intra-articular upper and lower extremity fractures. ⋯ Although subjective image quality is rated inferior compared to other imaging modalities, intra-operative use of 3D-fluoroscopy is a helpful diagnostic tool for improving the quality of reduction and implant position in intra-articular fractures.

Randomized Controlled Trial
Triple-rule-out dual-source CT angiography of patients with acute chest pain: dose reduction potential of 100 kV scanning.
To investigate the dose reduction potential of low kV triple-rule-out dual-source CT angiography (TRO-CTA) in non-obese (BMI ≤ 25 kg/m(2)) patients with acute chest pain. ⋯ TRO-CTA with 100 kV is feasible in non-obese patients and results in diagnostic image quality and significantly reduced radiation dose.

Non-traumatic chest pain is a common symptom in patients who present in the emergency department. From a clinical point of view, it is important to differentiate cardiac chest pain from non-cardiac chest pain (NCCP). ⋯ The presentation of pain plays an important role in narrowing the differential diagnosis and initiating further diagnostic management and treatment. As the benign causes tend to recur, and may lead to patient anxiety and great costs, a meticulous evaluation of the patient is necessary to diagnose the underlying disorder or disease.

High resolution magnetic resonance imaging (HRMRI) has been used as an imaging modality to depict the intracranial artery wall. The aim of this study was to compare images of the vessel wall between symptomatic and asymptomatic atherosclerotic plaques of the middle cerebral artery (MCA) using HRMRI. ⋯ HRMRI has the potential to distinguish between atherosclerotic plaques in symptomatic and asymptomatic MCA stenoses.
