Background: Cardiac computed tomography (CT) is increasingly used to search for cardioembolic sources of acute ischemic stroke (AIS). We assessed the association between high-risk cardioembolic sources on cardiac CT and AIS.
Methods: We performed a case-control study using data from a prospective cohort including consecutive adult patients with suspected stroke who underwent cardiac CT acquired during the initial stroke imaging protocol between 2018 and 2020.
Background: The PRAETORIAN score was developed as an alternative for defibrillation testing after subcutaneous implantable cardioverter-defibrillator implantation to assess 3 aspects of implant position on a bidirectional chest radiograph. The score is validated on a standard standing chest radiograph with arms elevated in the lateral view.
Objective: We aimed to evaluate the effect of different anatomic positions on the PRAETORIAN score.
Background: The Apple Watch has the capability to record a lead 1 electrocardiogram (ECG) and can identify and report atrial fibrillation. The use for detecting myocardial ischaemia is not endorsed by Apple but is documented in this case.
Case Summary: A 76-year-old man made a lead 1 ECG with his Apple Watch immediately after exercising on a cross trainer.

Article Synopsis
- A retrospective study evaluated the effectiveness of MRI, CT, and [F]FDG-PET-CT in detecting lymph node involvement in early-stage cervical cancer using data from the Netherlands Cancer Registry.
- The study included 1676 patients evaluated with MRI, 926 with CT, and 379 with [F]FDG-PET-CT, finding that [F]FDG-PET-CT had the highest sensitivity for detecting nodal metastases at 80%, compared to 48% and 40% for MRI and CT, respectively.
- While [F]FDG-PET-CT outperformed MRI and CT in sensitivity, MRI and CT had higher specificity, indicating that [F]FDG-PET
Objective: Treatment strategies for bulky lymph nodes in patients with locally advanced cervical cancer scheduled for definitive chemoradiation include nodal boosting with radiotherapy, surgical debulking, or both. The aim of this retrospective cohort study was to compare survival and toxicity in patients receiving these treatments and to compare them with a group that received neither form of treatment.
Methods: Women diagnosed between January 2009 and January 2017 with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB2, IIA2-IVA cervical cancer with lymph nodes ≥1.
