Segmental testicular infarction vs testicular tumour: the usefulness of the excisional frozen biopsy
We experienced a case in which a pulmonary arteriovenous fistula was found due to the occurrence of cerebral infarction. The patient was a 65-year-old female who had seen a local doctor for lightheadedness occurring upon rising in the morning. She underwent a cerebral MRI and was diagnosed to have a cerebral infarction. Upon closer examination, a chest radiograph revealed an abnormal shadow and...
OBJECTIVES We evaluated whether delayed contrast-enhanced magnetic resonance imaging (DCE-MRI) using an extracellular contrast agent could predict improvement of dysfunctional but viable myocardium after acute reperfused myocardial infarction (MI). BACKGROUND The transmural extent of hyperenhancement at DCE-MRI has been related to improvement of function in reperfused MI. However, evidence is s...
Pairs of ultrasonic dimension gauges and a micromanometer implanted in the subendocardium of the left ventricles of unanesthetized dogs were used to analyze serial changes in hemodynamic status and segmental function for up to 4 weeks after permanent circumflex coronary artery occlusion. Regional function was studied in control segments and in segments identified as marginal (hypokinetic) and i...
conclusion ped software of dual-source ct combined with perfusion imaging can significantly improve the detection rate of peripheral pulmonary embolism. results ctpa images revealed 50 (7.81%) segmental and 56 (4.38%) sub-segmental pulmonary embolisms, while the ped images showed 68 (10.63%) segmental and 94 (7.34%) sub-segmental pulmonary embolisms. thus, the detection rate on ped images for p...
