Feasibility of on-site CT-FFR analysis on cardiac photon-counting CT in evaluation of hemodynamically significant stenosis in comparison to invasive catheter angiography.

Objectives: Coronary CT angiography (CCTA) is an excellent tool in ruling out coronary artery disease (CAD) but tends to overestimate especially highly calcified plaques. To reduce diagnostic invasive catheter angiographies (ICA), current guidelines recommend CT-FFR to determine the hemodynamic significance of coronary artery stenosis. Photon-Counting Detector CT (PCCT) revolutionized CCTA and may improve CT-FFR analysis in guiding patients.

Background: Intraoperative ultrasound-guided breast-conserving surgery guarantees real-time direct visualization of tumor and resection margins. We compared surgical, oncologic, and cosmetic outcomes between intraoperative ultrasound-guided breast-conserving surgery and traditional (palpation- or wire-guided) surgery across all breast cancer lesion types.
Methods: This prospective observational cohort study was conducted at the Veneto Institute of Oncology between January 2021 and October 2022.

Dysuria, a feeling of pain or discomfort during urination, is often caused by urinary tract infection but can also be due to sexually transmitted infection, bladder irritants, skin lesions, and some chronic pain conditions. History is most often useful for finding signs of sexually transmitted infection, complicated infections, lower urinary symptoms in males, and noninfectious causes. Most patients presenting with dysuria should have a urinalysis performed.

Objective: The purpose of this study was to present a newly designed 3D-printed personalized model (3D PPM) of a radiofrequency needle guide with a maxillary fixation for gasserian ganglion (GG) puncture.
Methods: Implementation of 3D CT-guided radiofrequency therapy of the GG with and without use of 3D PPM was analyzed. The following parameters were assessed: radiation time, dose area product, air kerma reference point, pain severity during the puncture needle insertion, prosopalgia regression degree (according to visual analog scale) and the severity of facial numbness (according to the Barrow Neurological Institute scale) in the early postoperative period, and postpuncture complications.
Prognostic value of manual versus automatic methods for assessing extents of resection and residual tumor volume in glioblastoma.

1Department of Neurosurgery, St. Olav's University Hospital, Trondheim, Norway.
Objective: The extent of resection (EOR) and postoperative residual tumor (RT) volume are prognostic factors in glioblastoma. Calculations of EOR and RT rely on accurate tumor segmentations. Raidionics is an open-access software that enables automatic segmentation of preoperative and early postoperative glioblastoma using pretrained deep learning models.
