This review outlines technical advances in imaging of the small bowel. These include enhancement characteristics of normal bowel mucosa in computed tomography, contrast agents in magnetic resonance imaging, contrast ultrasonography, small-bowel transit measurements by radionuclide imaging, and enteroscopy. Subsequently, the application of these in clinical problem areas, including small-bowel obstruction, bleeding, and Crohn and celiac disease, will indicate the excellent potential of computed tomography, magnetic resonance imaging, and enteroscopy in particular.

Cone-beam computed tomography (CBCT) assisted bronchoscopy shows prospective advantages in diagnosing peripheral pulmonary lesions (PPLs), but its diagnostic value and potential influencing factors remain unclear. What is the clinical value and optimal strategy of CBCT-assisted bronchoscopy in diagnosing PPLs? The references were searched from PubMed, EmBase, and Web of Science. Studies reporting diagnostic yield and potential influencing factors of CBCT-assisted bronchoscopy were included.

This study aims to evaluate the implementation of concomitant CAD assessment on pre-TAVI (transcatheter aortic valve implantation) planning CTA (CT angiography) aided by CT-FFR (CT-fractional flow reserve) [The CT2TAVI protocol] and investigates the incremental value of CT-FFR to coronary CT angiography (CCTA) alone in the evaluation of patients undergoing CT2TAVI. This is a prospective observational real-world cohort study at an academic health system on consecutive patients who underwent CTA for TAVI planning from 1/2021 to 6/2022. This represented a transition period in our health system, from not formally reporting CAD on pre-TAVI planning CTA (Group A) to routinely reporting CAD on pre-TAVI CTA (Group B; CT2TAVI protocol).

Understanding the impact of premolar root anatomy, sex, and age on incisor complexity can aid in developing tailored diagnostic and therapeutic strategies. This study evaluated if the anatomical complexity of mandibular premolars, sex and age can predict the anatomical complexity in mandibular incisors. Using CBCT scans, 3944 mandibular incisors from 493 patients were analyzed.
