External validation of a CT score for predicting ischaemia in adhesive small-bowel obstruction.
Eur Radiol
January 2025
Department of Diagnostic and Interventional Radiology, François-Mitterrand University Hospital, Dijon, France.
Objectives: To assess the diagnostic accuracy, in a validation cohort, of a score based on three CT items, which has shown good performance for predicting ischaemia complicating acute adhesive small-bowel obstruction (SBO).
Methods: This retrospective single-centre study of diagnostic accuracy included consecutive patients admitted for acute adhesive SBO in 2015-2022, who were treated conservatively or underwent surgery within 24 h after CT. The gold standard for ischaemia was an intraoperative diagnosis for operated patients, while the absence of ischaemia was confirmed either by its absence during surgery or by clinical follow-up in patients who did not undergo surgery.

Under benign conditions, bone tissue can regenerate itself without external intervention. However, this regenerative capacity can be compromised by various factors, most importantly related with the extent of the injury. Critical-sized defects, exceeding the body's natural healing ability, demand the use of temporary or permanent devices like artificial joints or bone substitutes.

Eur Radiol
January 2025
Department of Radiology, Section of Nuclear Medicine, Leiden University Medical Center, Leiden, The Netherlands.
Objective: Metastatic castration-resistant prostate cancer (mCRPC) is a heterogeneous disease with varying survival outcomes. This study investigated whether baseline PSMA PET/CT parameters are associated with survival and treatment response.
Methods: Sixty mCRPC patients underwent [F]PSMA-1007 PET/CT before treatment with androgen receptor-targeted agents (ARTAs) or chemotherapy.
Evaluation of MRI characterisation of histopathologically matched lymph nodes and other mesorectal nodal structures in rectal cancer.
Eur Radiol
January 2025
Department of Diagnostics and Intervention, Diagnostic Radiology, Umeå University, Umeå, Sweden.
Purpose: To evaluate current MRI-based criteria for malignancy in mesorectal nodal structures in rectal cancer.
Method: Mesorectal nodal structures identified on baseline MRI as lymph nodes were anatomically compared to their corresponding structures histopathologically, reported as lymph nodes, tumour deposits or extramural venous invasion. All anatomically matched nodal structures from patients with primary surgery and all malignant nodal structures from patients with neoadjuvant treatment were included.

Feline leishmaniasis is increasingly recognized as a disease affecting cats worldwide, with notable prevalence in regions surrounding the Mediterranean Basin and in Brazil. An approximately one-year-old domestic shorthair cat was presented with small papules and nodules (2 mm) on the nasal planum. Physical examination and routine blood analyses were normal.
