Prospective head-to-head comparison of coronary calcium scores between standard computed tomography (CT) and photon-counting CT show no significant differences, while photon-counting CT administers substantially lower radiation dose.

Background: Goldenhar syndrome is a clinically heterogeneous disorder defined by a rare combination of congenital anomalies-an eye abnormality, in addition to two of the following three: ear anomalies, mandibular malformations, and vertebral defects. Notably, children with Goldenhar syndrome present with a high incidence of cervical spine malformations.
Clinical Case: In this report, we present an unusual case of a 15-year-old child with Goldenhar syndrome, who additionally presents with some clinical features of VACTERL syndrome.

The cerebral arterial circle morphologic variability has been extensively studied. The posterior cerebral artery (PCA) variants are rarely identified, except from the first segment (P1) hypoplasia or absence. Due to its unique morphology, the computed tomography angiography (CTA) of a 34-year-old female patient was further investigated.

Background And Aim: Treatment effects of a combined rapid maxillary expansion (RME) and Delaire facemask (DFM) therapy have so far only been scientifically investigated through cephalometric analyses. The combination of cephalometric, dental cast and cone-beam computed tomography (CBCT) scan analysis was not yet used for investigating morphologic changes of the tooth-bearing palate. The aim of the present study was to determine whether patient age at treatment begin has an influence upon palatal length changes after RME/DFM therapy, and to what extent transverse palatal sutures contribute to these.

Purpose: This study presents a MATrix LABoratory (MATLAB)-based methodology for calculating intracranial volumes from head computed tomography (CT) data and compares it with established methods.
Methods: Regions of interest (ROI) were manually segmented on CT images using a stylus pen, facilitated by mirroring a computer desktop onto a tablet. The volumetric process involved three main steps: (1) calculating the volume of a single voxel, (2) counting the total number of voxels within the segmented ROI, and (3) multiplying this voxel count by the single-voxel volume.

Objective: To develop a three-dimensional (3D) image based extended tumor plane technique for robotic-assisted partial nephrectomy (RAPN).
Methods: We prospectively enrolled patients with a local renal tumor for RAPN between March 2019 and Mar 2022. 3D virtual model was reconstructed based on the computed tomography urography.
