Hepatic arterial perfusion
WebAbstract Objective CT perfusion (CTp) values are affected by CT scan acquisition duration (t acq ); their reproducibility is adversely affected by uncertainty in their measurement. The objectives were to assess the effects of t acq on CTp parameter values in metastases from renal cell carcinoma (mRCC) in thoracic and abdominal locations. WebObjective: Our goal was to quantify absolute hepatic arterial and portal venous perfusion noninvasively in patients with and without liver disease using ultrafast CT. Materials and …
