Multimodality Imaging of Postmastectomy Breast Reconstruction Techniques, Complications, and Tumor Recurrence.

For women undergoing mastectomy, breast reconstruction can be performed by using implants or autologous tissue flaps. Mastectomy options include skin- and nipple-sparing techniques. Implant-based reconstruction can be performed with saline or silicone implants.

Cryoablation Therapy for Early-Stage Breast Cancer: Evidence and Rationale.

Recent advances in breast cancer research and treatment propel a paradigm shift toward less aggressive and less invasive treatment for some early-stage breast cancer. Select patients with small, low-risk tumors may benefit from a less aggressive approach with de-escalated local therapy. Cryoablation of breast cancer is an emerging nonsurgical treatment alternative to breast-conserving surgery.

Evaluation of a Deep Learning Reconstruction for High-Quality T2-Weighted Breast Magnetic Resonance Imaging.

Deep learning (DL) reconstruction techniques to improve MR image quality are becoming commercially available with the hope that they will be applicable to multiple imaging application sites and acquisition protocols. However, before clinical implementation, these methods must be validated for specific use cases. In this work, the quality of standard-of-care (SOC) T2w and a high-spatial-resolution (HR) imaging of the breast were assessed both with and without prototype DL reconstruction.

Spectrum of Mucin-containing Lesions of the Breast: Multimodality Imaging Review with Pathologic Correlation.

Mucin-containing lesions of the breast encompass a wide range of benign and malignant processes. The spectrum of histologic findings includes incidental mucus-filled benign cysts or ducts, mucocele-like lesions (MLLs), mucin-producing ductal carcinoma in situ, and invasive mucinous carcinoma. MLL is characterized by the presence of mucin-containing cysts that are typically associated with extravasated stromal mucin.

Low correlation between serum thyroglobulin and I radioiodine whole body scintigraphy: implication for postoperative disease surveillance in differentiated thyroid cancer.

Purpose: To evaluate postoperative serum thyroglobulin (Tg) as a reliable tumor marker in low-risk differentiated thyroid cancer (DTC).

Methods: Two hundred and three patients met the selection criteria of >18 years old; who had undergone total or near total thyroidectomy; had a postoperative Tg, and had undergone I pre ablation whole body scan (PA-WBS). The primary endpoint was the correlation between Tg level and functional remnant thyroid tissues.

Substantial interreader agreement for biopsy with reduction in biopsy rate: A multireader diagnostic performance study of ACR TI-RADS.

Purpose: To assess diagnostic performance of ACR TI-RADS in thyroid cancer detection and evaluate interobserver agreement among radiologists with lower interpreting experience.

Methods: Four radiologists retrospectively assessed 295 biopsied thyroid nodules from ultrasound studies performed between 2009 and 2019, blinded to histopathology. Diagnostic performance for cancer detection was determined individually, and interobserver agreement among four readers was evaluated with Fleiss kappa coefficient (ⱪ).

Single shot lymphoscintigraphy in breast cancer: Effective single tracer sentinel node detection protocol with reduction in procedural pain.

Purpose: Variation in protocols for axillary sentinel lymph node (SLN) mapping exists. We strive to evaluate the effectiveness of reduction in number of injections on reducing procedural pain, while maintaining nodal detection.

Methods: Over 7 years, the number of periareolar injections performed was reduced stepwise from 4 to 1.

Adding value to imaging services: a survey of patient and referring physician preferences for direct radiologic reporting of results.

Purpose: To identify preferences of patients and referring physicians for direct patient communication and notification of radiologic study results.

Methods: An anonymous survey was conducted of patients undergoing outpatient radiologic imaging studies and their referring physicians. The voluntary surveys elicited responses regarding preferences on a 5-point Likert scale (Strongly disagree, disagree, neutral, agree and strongly agree), as well as indicated by responding yes or no to specific questions.

Should Radiologists Comment on Incidental Findings of Vascular Calcifications Found on Abdominal/Pelvic CT in Patients Less Than 50 Years of Age?

Rationale And Objectives: To evaluate if incidental abdominopelvic calcified atherosclerosis (ACA) in patients under 50 years of age correlates with cardiovascular disease (CVD) risk factors. Most studies evaluating calcific atherosclerosis and associated increased risk of CVD have concentrated on middle age and older populations.

Materials And Methods: A retrospective review of 519 emergency department patients, aged 25-50 years, receiving computed tomography (CT) was performed and ACA correlated with lipid panels obtained via chart review.

Validation of PI-RADS Version 2 in Transition Zone Lesions for the Detection of Prostate Cancer.

Purpose To determine the association between Prostate Imaging Reporting and Data System (PI-RADS) version 2 scores and prostate cancer (PCa) in a cohort of patients undergoing biopsy of transition zone (TZ) lesions. Materials and Methods A total of 634 TZ lesions in 457 patients were identified from a prospectively maintained database of consecutive patients undergoing prostate magnetic resonance imaging. Prostate lesions were retrospectively categorized with the PI-RADS version 2 system by two readers in consensus who were blinded to histopathologic findings.

Evidence-based Comprehensive Approach to Forearm Arterial Laceration.

Introduction: Penetrating injury to the forearm may cause an isolated radial or ulnar artery injury, or a complex injury involving other structures including veins, tendons and nerves. The management of forearm laceration with arterial injury involves both operative and nonoperative strategies. An evolution in management has emerged especially at urban trauma centers, where the multidisciplinary resource of trauma and hand subspecialties may invoke controversy pertaining to the optimal management of such injuries.

Nuclear Myocardial Perfusion Imaging Versus Stress Echocardiography in the Preoperative Evaluation of Patients for Kidney Transplantation.

Unlabelled: The goal of this study was to evaluate the diagnostic accuracy, cost-effectiveness, and appropriate use of SPECT myocardial perfusion imaging (SMPI) versus stress echocardiography in the preoperative evaluation of patients for kidney transplantation.

Methods: A single-institution, retrospective study was performed. SMPI was performed with regadenoson and stress echocardiography predominantly with dobutamine.

Gram-negative groin sepsis treated with covered stents and systemic antibiotics.

Prosthetic graft infections are hazardous conditions. Those due to Gram-negative bacteria are particularly serious. When Gram-negative microorganisms are present, entire graft excision is recommended, with revascularization if needed, preferably with autogenous tissues or with prosthetic grafts via non-infected planes if autogenous options are not available.
