Comparative utility of preoperative imaging in normocalcemic versus hypercalcemic primary hyperparathyroidism.
This retrospective review examined the utility of preoperative imaging in normocalcemic versus hypercalcemic primary hyperparathyroidism (PHPT) patients. The review was conducted on all PHPT patients who underwent parathyroidectomy from 2001 to 2019. The cohort included 2218 patients, with 433 normocalcemic PHPT (19.5%) and 1785 hypercalcemic PHPT (80.5%). Among normocalcemic patients, there were no differences in cure rates in patients with preoperative imaging versus those without (100% vs 99%). There were no differences in postoperative complications except for a slight increase in transient hypocalcemia in patients without imaging. There were equivalent cure and complication rates for normocalcemic PHPT patients with or without preoperative imaging compared to hypercalcemic patients.

Updates in intraoperative strategies for enhancing intra-axial brain tumor control.
This review looked at recent advances in intraoperative strategies for enhancing intra-axial brain tumor control. The authors looked at published research centered on different innovative tools and techniques, including fluorescence-guided surgery, new methods of drug delivery, and minimally invasive procedural options.

Surgical skill can be objectively measured from fluoroscopic images using a novel image-based Decision Error Analysis (IDEA) score.
This study introduces and evaluates a novel Image-based Decision Error Analysis (IDEA) score that captures performance during fluoroscopically assisted wire navigation. Findings showed that the fluoroscopic images obtained in the course of placing a guide wire contained a rich amount of information related to surgical skill. The IDEA scoring provided a basis for evaluating the competence of a resident. The score can be used to assess skill at key timepoints throughout residency, such as when rotating onto/off of a new surgical service and before performing certain procedures in the operating room, or as a tool for debriefing/providing feedback after a procedure is completed.

Characterising potential bone scan overuse amongst men treated with radical prostatectomy.
The authors characterized bone scan use after radical prostatectomy (RP) using data from a large, national integrated delivery system. They found a substantial rate of bone scan utilization after RP. The majority were performed for prostate-specific antigen levels in which the likelihood of a positive test was low. They recommended more judicious use of imaging in the post-RP setting.

Diagnostic and prognostic value of myocardial blood flow quantification as non-invasive indicator of cardiac allograft vasculopathy.
Cardiac allograft vasculopathy (CAV) is a leading cause of death in orthotopic heart transplant (OHT) survivors. Effective non-invasive screening methods are needed. The aim of this study was to investigate the added diagnostic and prognostic value of myocardial blood flow (MBF) to standard myocardial perfusion imaging (MPI) with positron emission tomography (PET) for CAV detection.

Perioperative considerations for chylothorax.
This paper presents the case report of a 73 year old man with recurrent right pleural effusions, and a mediastinal mass of indeterminate etiology after a computer tomography-guided biopsy and thoracentesis. It discusses the perioperative considerations for chylothorax.

Emergency department imaging modality effect on surgical management of nephrolithiasis: a multicenter, randomized clinical trial.
In this multicenter randomized clinical trial the inivestigators examined rates of urological referral and intervention to elucidate whether the initial diagnostic imaging modality affected the management of nephrolithiasis. They concluded that patients undergoing a urological intervention who had ultrasonography as initial imaging did not experience a significant delay to intervention or different procedure types, but the majority ultimately underwent computerized tomography before surgery.
