Students in medical and non-medical fields held different views on DNR. A majority of participants considered the patient's own wish as most important in DNR decisions. Family wishes were considered less important than the patient's own wishes.

Contrast-enhanced magnetic resonance imaging (MRI) is widely used for diagnosing various benign breast lesions. Such lesions can exhibit benign or suspicious MRI features, and may mimic malignancy. To facilitate patient care, radiologists should familiarise themselves with MRI features of benign breast lesions. This study discusses common benign breast lesions including breast cyst, fibrocystic change, breast abscess, intramammary lymph node, fat necrosis, fibroadenoma, solitary and multiple intraductal papillomas, stromal fibrosis, parenchymal scar, diabetic mastopathy, injection mammoplasty with granuloma formation, cutaneous lesion, and normal anatomic variant mimicking a mass.

Stercoral colonic perforation is one of the causes of 'spontaneous' colonic perforation. Stercoral colonic perforation is well reported in the surgical and gastroenterology literature, yet little has been published in the radiology literature. This report describes two patients with stercoral perforation of the sigmoid colon and faecal peritonitis. The aetiology, pathophysiology, and imaging findings of this rare, but fatal, condition are reviewed.

Introduction:Precise preoperative localisation is essential for nonpalpable breast lesions undergoing lumpectomy. Hookwire localisation has been gradually replaced by radioisotope-guided occult lesion localisation (ROLL). We aimed to evaluate the use of magnetic metal markers (Magseed) as a nonradioactive and wireless alternative. Methods: We compared cases of Magseed localisation performed between September 2018 and April 2020 with the same number of ROLL procedures with identical pathology in the same period. Results: In total, 24 Magseed and 24 ROLL procedures were included. There were no significant differences between the case groups in terms of target characteristics, operation time, specimen size, pathological diagnosis, margin clearance, or reoperation rate. Localisation duration was significantly shorter in ROLL procedures (8.7 min) compared with Magseed localisation (12.9 min, p < 0.0001). No complications were reported. Same-day surgery was performed in all ROLL and 17 Magseed lesions. The localisation-operation interval for the other seven Magseed lesions were 4 to 14 days. Significantly lower intraoperative re-excision rates (p = 0.006) were observed in the Magseed group (8.3%) compared with the ROLL group (45.8%). Technical success of the ROLL group was 100%. Twenty-two (91.7%) Magseed localisations achieved technical success with 11/11 (100%) using ultrasound and 11/13 (84.6%) using stereotactic guidance. Magseed displacement was up to 4.8 mm in the localisation-operation interval. Conclusion: Magseed is a safe and effective localisation technique for nonpalpable breast lesions, which allows decoupling of radiological and surgical schedules.
