Prospective Study of Supplemental Screening With Contrast-Enhanced Mammography in Women With Elevated Risk of Breast Cancer: Results of the Prevalence Round.

Purpose: Contrast-enhanced mammography (CEM) and magnetic resonance imaging (MRI) have shown similar diagnostic performance in detection of breast cancer. Limited CEM data are available for high-risk breast cancer screening. The purpose of the study was to prospectively investigate the efficacy of supplemental screening CEM in elevated risk patients.

Contrast Enhanced Mammography in Routine Clinical Practice: Frequency and Malignancy Rates of Enhancing Otherwise Occult Findings.

Background: In routine clinical practice, contrast-enhanced mammography (CEM) examinations identify enhancing findings seen only on subtraction images that have no low-energy mammographic or sonographic correlate. The purpose of this study is to report the frequency and malignancy rates of enhancing findings seen only on subtraction images in a tertiary care breast imaging practice.

Materials And Methods: Consecutive review of CEM exams from December 2015 to May 2020.

Performance of an algorithm for diagnosing acute cholecystitis using clinical and sonographic parameters.

Purpose: Identify an algorithm using clinical and ultrasound (US) parameters with high diagnostic performance for acute cholecystitis.

Methods: Consecutive emergency department (ED) patients from 4/1/2019 to 12/31/2019 were retrospectively reviewed to record non-US parameters and make US observations. Outcomes were categorized as either: (1) acute cholecystitis; or (2) negative acute cholecystitis.

Contrast-Enhanced Mammography for Newly Diagnosed Breast Cancer in Women With Breast Augmentation: Preliminary Findings.

In 17 women with newly diagnosed breast cancer who underwent contrast-enhanced mammography (CEM) and MRI, both modalities were found to be concordant for the index cancer. In six of the 17 women, CEM showed an additional lesion that was confirmed by MRI. Of these six additional lesions, three were multifocal, one was multicentric, and two were contralateral; two of the six were malignant.

Comparison of Open and Robot Assisted Radical Nephrectomy With Level I and II Inferior Vena Cava Tumor Thrombus: The Mayo Clinic Experience.

Objective: To compare the perioperative and oncologic outcomes associated with open radical nephrectomy with tumor thrombus (O-RNTT) vs robot assisted radical nephrectomy with tumor thrombus (RA-RNTT). Renal cell carcinoma with venous tumor thrombus has traditionally been managed through an open surgical approach. The robot assisted approach may offers improved perioperative outcomes compared to open, but there are few studies comparing these 2.

Demonstration of 99mTc-MDP Uptake in a Mobile Urinary Bladder Calculus on SPECT/CT.

We report a large mobile bladder calculus with intense Tc-MDP uptake demonstrated on both whole-body bone scintigraphy and SPECT/CT images in a patient with complicated chronic history of urolithiasis and urinary tract infection. Bone tracer uptake in bladder calculus is a rare phenomenon and might be related to the composition and matrix of calculus, direct exposure to excreted radiotracer, and bacterial colonization on the surface of calculus.

Robot Assisted Surgery of the Vena Cava: Perioperative Outcomes, Technique, and Lessons Learned at The Mayo Clinic.

This study aims to describe robot assisted surgery of the inferior vena cava (IVC) by assessing techniques utilized, perioperative outcomes, complications, and long-term patency of the IVC. A retrospective review was performed on all robotic surgeries involving dissection and repair of the IVC at our institution. Patient characteristics, operative reports, and follow-up visits were analyzed.

Robot Assisted Radical Cystectomy vs Open Radical Cystectomy: Over 10 years of the Mayo Clinic Experience.

Objectives: There is scant information about intermediate / long-term comparative outcomes between robot assisted radical cystectomy (RARC) and open radical cystectomy (ORC). The purpose of this study is to present survival and oncological outcomes between bladder cancer patients who undergo RARC vs. ORC with an overall median follow-up of over 5 years.

Initial Experience of Tomosynthesis-Guided Vacuum-Assisted Biopsies of Tomosynthesis-Detected (2D Mammography and Ultrasound Occult) Architectural Distortions.

Objective: As experience and aptitude in digital breast tomosynthesis (DBT) have increased, radiologists are seeing more areas of architectural distortion (AD) on DBT images compared with standard 2D mammograms. The purpose of this study is to report our experience using tomosynthesis-guided vacuum-assisted biopsies (VABs) for ADs that were occult at 2D mammography and ultrasound and to analyze the positive predictive value for malignancy.

Materials And Methods: We performed a retrospective review of 34 DBT-detected ADs that were occult at mammography and ultrasound.

Rationale for catheter directed therapy in pulmonary embolism.

Pulmonary embolism (PE) is a widespread health concern associated with major morbidity and mortality. Catheter directed therapy (CDT) has emerged as a treatment option for acute PE adding to the current potential options of systemic thrombolysis or anticoagulation. The purpose of this review is to understand the rationale and indications for CDT in patients with PE.

May-Thurner: diagnosis and endovascular management.

Common left iliac vein compression, otherwise known as May-Thurner (MT), is an anatomical risk factor for lower extremity deep vein thrombosis (DVT). MT refers to chronic compression of the left iliac vein against the lumbar spine by the overlying right common iliac artery. The compression may be asymptomatic.

Contrast-enhanced Digital Mammography: A Single-Institution Experience of the First 208 Cases.

Contrast-enhanced digital mammography (CEDM) is the only imaging modality that provides both (a) a high-resolution, low-energy image comparable to that of digital mammography and (b) a contrast-enhanced image similar to that of magnetic resonance imaging. We report the initial 208 CEDM examinations performed for various clinical indications and provide illustrative case examples. Given its success in recent studies and our experience of CEDM primarily as a diagnostic adjunct, CEDM can potentially improve breast cancer detection by combining the low-cost conclusions of screening mammography with the high sensitivity of magnetic resonance imaging.

Factors Contributing to the Success of Ultrasound-Guided Native Renal Biopsy.

Objectives: The purpose of this study was to evaluate factors contributing to the success of ultrasound-guided native renal biopsy.

Methods: We retrospectively identified patients who had ultrasound-guided native renal biopsy at our institution over a 10-year period. We reviewed the imaging and electronic medical records to collect demographic information and clinical data, including pathologic results.

Risk of bleeding after native renal biopsy as a function of preprocedural systolic and diastolic blood pressure.

Purpose: To determine the risk of bleeding complications after native renal biopsy as a function of preprocedural blood pressure (BP).

Materials And Methods: A total of 293 patients (163 men; mean age, 59.1 y) who underwent ultrasound-guided native kidney biopsy at a single institution over a 10-year period were retrospectively identified.

Successful coil embolization of circumflex iliac artery pseudoaneurysms following paracentesis.

Abdominal paracentesis complicated by perforation of a penetrating arterial branch is an extremely rare complication. We report 2 patients who presented with abdominal wall pseudoaneurysms following abdominal paracentesis for the evaluation and treatment of their hepatic dysfunction. We subsequently review the treatment modalities and interventions performed in each case.

US-guided renal transplant biopsy: efficacy of a cortical tangential approach.

Purpose: To describe the cortical tangential approach to ultrasonographically (US) guided renal transplant biopsy and evaluate its efficacy in obtaining sufficient cortical tissue.

Materials And Methods: This HIPAA-compliant retrospective study was exempted from review by the institutional review board. Informed consent was not required.

Accuracy of ultrasound in estimation of prostate weight: comparison of urologists and radiologists.

Introduction: Measurements of prostate size are obtained to contribute in the diagnosis and follow up of patients with a variety of diseases. Since its introduction, transrectal ultrasonography (TRUS) of the prostate has become the most common method for assessment of prostate volumes. Ultrasonography, in general, has been associated with concerns of operator dependent variability.
