Background: With regionalization of care, patients often undergo treatment in institutions other than where the initial investigation is conducted. This study assessed the impact of a shared diagnostic imaging repository (SDIR) on processes of care and outcomes in hepato-pancreatico-biliary (HPB) cancer surgery.
Methods: Provincial administrative datasets were linked to study HPB cancer patients operated at a regional cancer centre (2003-2014). SDIR and non-SDIR groups were based on where initial imaging (CT or MRI) was conducted. Outcomes were repeat imaging before surgery and wait times for surgery from initial imaging and surgical consultation.
Results: Of 839 patients, 474 were from SDIR institutions. Fewer SDIR patients underwent any repeat imaging (55.9% vs. 75.3%; p < 0.01) and repeat imaging with same modality and protocol (24.7% vs. 43.0%; p < 0.01). Median wait time to surgery from initial imaging (64 Vs. 79 days; p < 0.01) and surgical consultation (39 Vs. 45 days; p = 0.046) was shorter with SDIR. SDIR patients had lower adjusted odds of any repeat imaging (OR 0.20 [0.14-0.30]), and repeat imaging with same modality and protocol (OR 0.58 [0.41-0.80]).
Conclusion: Radiology sharing with SDIR reduced repeat imaging for HPB cancer surgery, including potentially redundant repeat imaging with same protocol, and shortened wait time to surgical care.

Limited available evidence comparing DOACs with warfarin suggests efficacy and safety of DOACs for CVT. We aimed to evaluate whether a specific DOAC is preferred for the treatment of CVT. This retrospective cohort study included adult patients with CVTs between September 2018 and September 2022 treated with a DOAC.

This case report describes a 70-year-old male presenting with limb weakness, urinary retention and tandem cervical and lumbar spinal stenosis with complicating white cord syndrome, a rare reperfusion injury post decompression surgery. Initially admitted following an unwitnessed fall, the patient's neurological examination indicated that progressive weakness of the limbs and sensory loss etiology is cervical and lumbar spondylosis with severe spinal canal stenosis, confirmed by imaging. Due to rapid deterioration, he underwent C5 corpectomy, cervical decompression and fusion.

In the era of molecular testing, thyroid nodules with indeterminate cytology are increasingly being managed nonoperatively. The false-negative rates of these molecular tests, and therefore missed malignancies, are not well defined in real-world clinical practice. This retrospective study of patients undergoing fine needle aspiration (FNA) biopsy at our health system between November 2017 and March 2022 included nodules with The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) III and IV cytology and negative, currently negative, or negative but limited ThyroSeq version 3 (TSv3) results.

Introduction: Equivocal or negative pituitary magnetic resonance imaging (MRI) findings raise a significant challenge in the management of persistent or recurrent Cushing's disease (CD), compromising the chances of success of a further transsphenoidal surgery (TSS). The aim of our study was to determine the diagnostic utility of 11C-methionine (MET) positron emission tomography coupled with computerized tomography (PET/CT) in localizing the residual or relapsing corticotroph adenoma.
Methods: We retrospectively analyzed the results of 11C-MET PET/CT performed in two tertiary medical centers between May 2002 and November 2023 in 22 patients with a persisting or recurrent CD after initial TSS and equivocal or negative pituitary MRI findings.

Automatic segmentation of angiographic structures can aid in assessing vascular disease. While recent deep learning models promise automation, they lack validation on interventional angiographic data. This study investigates the feasibility of angiographic segmentation using in-context learning with the UniverSeg model, which is a cross-learning segmentation model that lacks inherent angiographic training.
