Automatic segmentation of hepatocellular carcinoma (HCC) in Digital Subtraction Angiography (DSA) videos can assist radiologists efficient diagnosis HCC and accurate evaluation tumors clinical practice. Few studies have investigated from DSA videos. It shows great challenging due to motion artifacts filming, ambiguous boundaries tumor regions high similarity imaging other anatomical tissues. In...

BACKGROUND Angiotensin II type 1 receptor (AT1R) is responsible for cardiovascular effects mediated by angiotensin II. This study aimed to investigate the impact of antibodies directed against AT1R (anti-AT1R) in renal allograft rejection. METHODS We evaluated 53 patients who had biopsy-proven rejection including antibody-mediated rejection (AMR) (N=22), T-cell-mediated rejection (TCMR) (N=29...

OBJECTIVES To evaluate the accuracy of routinely available non-invasive tests (spiral computed tomographic angiography (CTA), time of flight magnetic resonance angiography (MRA), and colour Doppler ultrasound (DUS)), individually and together, compared with intra-arterial digital subtraction angiography (DSA) in patients with symptomatic tight carotid stenosis; and to assess the effect of subst...

Introduction The aim of this study was to compare magnetic resonance angiography (MRA) with digital subtraction angiography (DSA) in the preoperative assessment of crural arteries and their skin perforators prior to free fibular transfer. Patients and methods Fifteen consecutive patients, scheduled for free vascularized fibular flap transfer, were subjected to DSA as well as MRA of the crural a...

The purpose of the investigation was to evaluate the diagnostic value of duplex ultrasonography (DU) of the cerebral arteries in the patients with cerebrovascular insufficiency performed in private offices in Zagreb town. The investigation was performed for all patients referred to digital subtraction angiography (DSA) after DU examination performed in one of private offices (in total, 12 offic...

for Subarachnoid Hemorrhage The American Journal of Neuroradiology shows different attitudes to state-of-the-art imaging with CT angiography (CTA) after subarachnoid hemorrhage. Kallmes et al opine that CTA should not be done for subarachnoid hemorrhage, whereas Lubicz et al document state-of-the-art CTA imaging of aneurysms. Kallmes et al enshrine selective conventional angiography (DSA), beli...

OBJECTIVE The use of digital subtraction angiography (DSA) for semiquantitative cerebral blood flow(CBF) assessment is a new technique. The aim of this study was to determine whether patients with aneurysmal subarachnoid hemorrhage (aSAH) with higher Hunt and Hess grades also had higher angiographic contrast transit times (TTs) than patients with lower grades. METHODS A cohort of 30 patients ...

Abstract Background and Aims ABO-incompatible kidney transplantation has been associated with an increased risk for antibody-mediated rejection (ABMR) early graft loss attributable to isoagglutinins. Its impact on the development of de novo donor-specific HLA antibodies (DSA) DSA-induced chronic ABMR, however, remains less well studied. Method We analyzed 297 transplant recipients (KTRs) who un...
