Yttrium-90 ((90)Y)-microspheres administered via the hepatic artery has been used for the treatment of unresectable primary or metastatic cancer in the liver. Prior to (90)Y therapy, however, the (90)Y administered activity and the percent shunting to lungs must be determined, most commonly by gamma camera imaging of technetium-99m ((99m)Tc)-macroaggregated albumin (MAA). The purpose of the cur...

SARS-CoV-2 (COVID-19) infection is a current public health problem that has been shown to cause multiple complications, including pulmonary thromboembolism. The first presented case 59-year-old woman with history of COPD, paroxysmal atrial fibrillation and COVID-19 in September 2020, consultation December 2020 for atypical chest pain suspected PE, AngioCT vessels was performed negative emboli, ...

Poly(N-isopropylacrylarnide-CO-methacrylic acid) P(NIPArn/MAA) nanoparticles were investigated as potentiai targetable systems for intravenous drug delivery. The responsive properties of P(NIPAm/MAA) nanoparticles have been characterized using dynamic light scattering (DLS) and responsive adhesion techniques. The hydrodynamic diameter of the nanoparticles decreased with increasing temperature o...

Key words: continuous ambulatory peritoneal dialysis confirmed a massive left-sided pleural effusion (Figure 1a). The echocardiogram revealed concentric (CAPD); end-stage renal disease (ESRD); hydro-thorax; Tc-99m macroaggregated human albumin left ventricular hypertrophy with adequate global performance , and no pericardial effusion. The abdominal (MAA) peritoneal scintigraphy sonogram showed ...

UNLABELLED Before (166)Ho radioembolization, a small batch of the same type of microspheres is administered as a scout dose instead of the conventional (99m)Tc-macroaggregated albumin ((99m)Tc-MAA). The (166)Ho scout dose provides a more accurate and precise lung shunt assessment. However, in contrast to (99m)Tc-MAA, an unintended extrahepatic deposition of this β-emitting scout dose could infl...

Hepatopulmonary syndrome is defined as the clinical triad of advanced liver disease, arterial deoxygenation and intrapulmonary vascular dilatation. Its pathogenesis is not completely understood. Excessive pulmonary nitric oxide production seems to be one of the factors that contribute to the intrapulmonary vascular dilatation. Other mediators such as endothelin-1 and the heme oxygenase-1/carbon...

BACKGROUND & AIMS Efficacy of radioembolization is derived from radioinduced damage, whereas tumour dosimetry is not considered as yet in prospective clinical trials. OBJECTIVES This study evaluates the impact of tumour dose (TD), based on 99m Tc macroaggregated albumin (MAA) quantification, on response and overall survival (OS). MATERIALS AND METHODS We consecutively included 85 patients w...
