Thirty-three patients with primary and secondary tumors of the liver were examined by computer-tomographic arteriography. Methods of selective intraarterial amplification of a computer-tomographic image is presented, as are indications for and contraindications against the use of such technique. The authors have united on a single working place a computer-aided tomographer Somatom DR-2 and a Siremobil device, this essentially simplifying the examinations. Selective administration of a contrast agent through a catheter into the celiac trunk helped significantly augment the density (200-240 U) of liver parenchyma, this permitting the detection of focal liver involvement undetectable by standard computer tomography because of a density similar to that of liver parenchyma. The method permitted the detection of foci 3-5 mm in diameter. On the whole use of computer-tomographic arteriography helped improve the diagnosis of focal liver involvement by 27%.

November 2024
Department of Spine Surgery, The First Affiliated Hospital, Fujian Medical University, Fuzhou, China; Department of Orthopedic Surgery, National Regional Medical Center, Binhai Campus of the First Affiliated Hospital, Fujian Medical University, Fuzhou, China. Electronic address:
Objective: To evaluate internal carotid artery's (ICA) anatomical relationships with atlantoaxial joints and posterior pharyngeal wall and to illustrate ICA injury risk during transoral procedures to the upper cervical spine.
Methods: Cervical spine computed tomography angiography of 238 patients was retrospectively evaluated. Each ICA was classified into 1 of 3 zones: areas medial (Zone 1), anterior (Zone 2), or lateral (Zone 3) to the atlantoaxial joint.
Medical-Surgical Implications of Branching Variation of Human Aortic Arch Known as Bovine Aortic Arch (BAA).

Department of Medical Specialties I, "Grigore T. Popa" University of Medicine and Pharmacy, 700115 Iasi, Romania.
(1) Background: The aortic arch (AA) branching model is challenging, considering the multiple anatomical variations documented in existing research. The bovine aortic arch (BAA) is the most prevalent anatomical variation among these. This variant of AA branching has long been considered a nonsymptomatic malformation, having been discovered incidentally during imaging investigations for other causes.

Department of Public Health, University of Naples "Federico II", Naples, Italy.
Objectives: To evaluate the diagnostic accuracy of the aortic dissection detection risk score (ADD-RS) used alone or in combination with D-dimer for detecting acute aortic syndrome (AAS) in patients presenting with symptoms suggestive of AAS.
Methods: We searched MEDLINE, EMBASE, and the Cochrane Library from inception to February 2024. Additionally, the reference lists of included studies and other systematic reviews were thoroughly searched.
Short-term mortality prediction in acute pulmonary embolism: Radiomics values of skeletal muscle and intramuscular adipose tissue.
J Cachexia Sarcopenia Muscle

Department of Radiology, Neuroradiology and Nuclear Medicine, Johannes Wesling University Hospital, Ruhr University Bochum, Bochum, Germany.
Background: Acute pulmonary embolism (APE) is a potentially life-threatening disorder, emphasizing the importance of accurate risk stratification and survival prognosis. The exploration of imaging biomarkers that can reflect patient survival holds the potential to further enhance the stratification of APE patients, enabling personalized treatment and early intervention. Therefore, in this study, we develop computed tomography pulmonary angiography (CTPA) radiomic signatures for the prognosis of 7- and 30-day all-cause mortality in patients with APE.

Rationale And Objectives: To evaluate the potential to reduce the amount of iodinated contrast media (CM) for computer tomographic pulmonary angiography (CTPA) with a novel photon-counting-detector CT (PCCT).
Materials And Methods: Overall, 105 patients referred for CTPA were retrospectively included in this study. CTPA was performed using bolus tracking and high-pitch dual-source scanning (FLASH mode) on a novel PCCT (Naeotom Alpha, Siemens Healthineers).
