Purpose: Our study aimed to obtain clinical indication-based typical dose values and size-specific dose estimates (SSDEs) for multiphasic abdominopelvic computed tomography (CT) examinations and to review our data with published diagnostic reference levels (DRLs).

Methods: In this retrospective study, multiphasic liver, kidney, pancreas, and mesenteric ischemia protocol CT scans performed at our center between January 2018 and December 2021 were analyzed. The clinical indications were hepatocellular carcinoma, renal cell carcinoma, pancreas adenocarcinoma, and mesenteric ischemia.

Article Synopsis
  • - The study analyzed over 8,400 adults over 40 to see how the sizes of brain arteries correlate with dementia and stroke risk using MRI scans.
  • - Findings showed that larger overall and carotid artery diameters significantly increase the risk of dementia (up to 1.74 times) and stroke (up to 2.11 times for basilar arteries).
  • - The results suggest that measuring brain artery sizes through MRI could be a valuable tool for predicting dementia and stroke risk across different populations.

Article Synopsis
  • The study investigates the link between red blood cell (RBC) concentrations, measured as hematocrit, and lacunar infarcts—small brain lesions related to ischemic stroke—using two groups: stroke-free adults and acute stroke patients.
  • Results showed that in stroke-free older adults, there is a U-shaped relationship, meaning both low and high hematocrit levels are associated with chronic covert lacunar infarcts.
  • In acute stroke patients, the study found a direct correlation where higher hematocrit levels were linked to an increased occurrence of acute lacunar strokes, suggesting that RBC concentrations might play a significant role in both chronic and acute brain injury.

Article Synopsis
  • Successful synchronized direct current cardioversion (DCCV) requires sufficient current delivery, but optimal current levels for effective DCCV remain undefined.
  • A study analyzed data from 220 patients who underwent DCCV, revealing that factors like body mass index (BMI), being female, sleep apnea, and chronic kidney disease are linked to higher transthoracic impedance (TTI).
  • Results suggest that understanding these factors can aid in determining the right shock energy needed for patients undergoing DCCV, particularly for conditions like atrial fibrillation and flutter.

Article Synopsis
  • The study aimed to explore how intracranial arterial calcification (IAC) relates to intracranial large artery stenosis (ILAS) and the likelihood of experiencing vascular events and mortality.
  • Researchers used data from two different cohorts, one from a stroke registry and another from a community study, analyzing CT scans and MRI/MRA results to assess IAC and its impact on health outcomes.
  • Findings revealed that IAC is significantly linked to both symptomatic and asymptomatic forms of ILAS and associated with increased mortality, though its connection to stroke risk was uncertain.
