The importance of computed tomography (CT) in the diagnosis of infectious spondylitis is reviewed on the basis of the currently available literature and our updated experience. The etiology and pathogenesis of the various types of presentation is briefly discussed. CT is an excellent non-invasive modality offering easy evaluation of the intra and extraosseous extent of the lesion, guidance to biopsy and in following therapeutic results. CT is compared with conventional techniques and its diagnostic value discussed in both the early and progressive stages of the disease.

Epilepsy Stands Nearby: A Pilot CT Perfusion Study on Post-Stroke Non-Convulsive Status Epilepticus.
Eur J Neurol
February 2025
IRCCS Istituto delle Scienze Neurologiche di Bologna, Department of Neurology and Stroke Center, Maggiore Hospital, Bologna, Italy.
Background: To investigate the relevance of hyperperfusion on computerised perfusion imaging (CTP) in the emergency setting in people with non-convulsive status epilepticus (NCSE) and previous stroke, to derive relevant aspects on the epileptogenic focus and the network recruited for NCSE propagation.
Methods: We enrolled consecutive adult patients with acute-onset NCSE and a previous stroke at a single institution undergoing CTP and EEG during symptoms. All patients underwent standard imaging including CT, CTP, CT angiograms and standard EEG within 30 min from hospital arrival.
A simple algorithm to derive virtual non-contrast electron density from dual-energy computed tomography data for radiotherapy treatment planning.

Department of Chemistry, Faculty of Science, Hokkaido University, Sapporo, Hokkaido, Japan.
Background: The use of iodinated contrast-enhancing agents in computed tomography (CT) improves the visualization of relevant structures for radiotherapy treatment planning (RTP). However, it can lead to dose calculation errors by incorrectly converting a CT number to electron density.
Purpose: This study aimed to propose an algorithm for deriving virtual non-contrast (VNC) electron density from dual-energy CT (DECT) data.
Improved display and detection of small renal stones using photon-counting detector CT compared to conventional energy-integrating detector CT.
Abdom Radiol (NY)

Mayo Clinic, Rochester, MN, USA.
Purpose: To compare same-day photon-counting detector CT (PCD-CT) to conventional energy-integrating detector CT (EID-CT) for detection of small renal stones (≤ 3 mm).
Methods: Patients undergoing clinical dual-energy EID-CT for known or suspected stone disease underwent same-day research PCD-CT. Patients with greater than 10 stones and no visible stones under 3 mm were excluded.
Multilevel support-assisted prototype optimization network for few-shot medical segmentation of lung lesions.
Sci Rep

Shandong Provincial Public Health Clinical Center, Shandong University, Jinan, 250013, Shandong, China.
Medical image annotation is scarce and costly. Few-shot segmentation has been widely used in medical image from only a few annotated examples. However, its research on lesion segmentation for lung diseases is still limited, especially for pulmonary aspergillosis.

Department of Oral and Maxillofacial Surgery (Head: Prof. Dr. Dr. Bernd Lethaus), University Hospital Tübingen, Eberhard Karls Universität Tübingen, Osianderstr. 2-8, D-72076, Tübingen, Germany.
Objectives: The aim of the present study was to compare the accuracy of fully guided implant insertion in vitro achieved by two fabrication methods in a cohort of undergraduates. We hypothesized that both methods achieve a comparable accuracy.
Methods: Surface scans and cone beam computed tomography images of 48 mandibular models were matched.
