The detection of calcified plaques is an essential step in the assessment of coronary heart diseases. However, manual plaque segmentation is subjected to intra- and inter-observer variability. We present a novel framework for the automatic detection of calcified coronary plaques in Computed Tomography images. In contrast to the state-of-the-art, both the native and the angio data sets are included to gain additional information about each plaque for its detection and subsequent assessment. The framework was successfully tested on 127 patients where 85.5% of the calcified and 96% of the obstructive plaques have been detected.

Background: The clinical outcomes of percutaneous coronary intervention (PCI) using drug-coated balloons (DCB) for de novo coronary artery lesions with eruptive calcified nodules remain unclear.
Methods And Results: This retrospective study analyzed the long-term outcomes of 308 consecutive patients (389 lesions) treated with PCI using DCB under optical coherence tomography guidance for de novo coronary artery lesions between September 2018 and November 2020. Patients were classified into 2 groups: those with an eruptive calcified nodule in the culprit lesion (CN group) and those without (non-CN group).

Background: Calcification of the radial artery is one of the main causes of anastomotic stenosis in autogenous arteriovenous fistulas in uremic patients. However, the pathogenesis of calcification is still unknown. This study attempted to screen and validate the risk factors for vascular calcification in patients with uremia.

Aims: Calcified chondroid mesenchymal neoplasm (CCMN) is a recently identified category of soft tissue neoplasms defined by cartilage or cartilaginous matrix formation and gene fusions. Its rarity and similarities to other soft tissue tumours pose diagnostic challenges. This study aims to deepen understanding of CCMN, highlighting molecular pathology's role in diagnosis to reduce misdiagnosis, overdiagnosis and overtreatment.

Introduction: This article presents the fourth detection of macroscopic cystic lesions due to sarcocystosis in domestic pigs during routine meat inspection worldwide, and the first molecular detection of in a domestic pig in Poland. Pigs can become intermediate hosts for by accidental ingestion of oocysts or sporocysts present in food or water contaminated by the faeces of canids (definitive hosts).
Material And Methods: The affected swine showed no clinical symptoms such as weight loss, dermatitis or dyspnoea suggesting sarcocystosis.
