Abbreviated Versus Multiparametric Prostate MRI in Active Surveillance for Prostate-Cancer Patients: Comparison of Accuracy and Clinical Utility as a Decisional Tool.

(1) Purpose: To compare the diagnostic accuracy between full multiparametric contrast-enhanced prostate MRI (mpMRI) and abbreviated dual-sequence prostate MRI (dsMRI) in men with clinically significant prostate cancer (csPCa) who were candidates for active surveillance. (2) Materials and Methods: Fifty-four patients with a diagnosis of low-risk PCa in the previous 6 months had a mpMRI scan prior to a saturation biopsy and a subsequent MRI cognitive transperineal targeted biopsy (for PI-RADS ≥ 3 lesions). The dsMRI images were obtained from the mpMRI protocol.

Diagnosis of clinically significant prostate cancer after negative multiparametric magnetic resonance imaging.

Introduction: The diagnostic pathway after a negative magnetic resonance imaging (nMRI) exam is not clearly defined. The aim of the present study is to define the risk of prostate adenocarcinoma (PCa) at the prostate biopsy after a negative multiparametric magnetic resonance imaging (mpMRI) exam.

Material And Methods: Patients with nMRI Prostate Imaging Reporting & Data System (PI-RADS) ≤2 and without a previous diagnosis of PCa were identified among all patients undergoing mpMRI in a single referral center between 01/2016-12/2019.

Transitional cell carcinoma recurrence impacting intestinal diversion after radical cystectomy. Oncologic outcomes of a rare site of recurrence.

Introduction: Transitional cell carcinoma recurrence within an intestinal urinary diversion (TCCUD) after radical cystectomy (RC) is a rare condition with unknown origin, prognosis and treatment. The aim of this study was to describe treatment options and oncologic outcomes of this understudied site of recurrence in a multi-institutional case series.

Material And Methods: TCCUD relapse cases after RC were investigated in a retrospective, multi-institutional study.

Case 257: Leiomyosarcoma of the Inferior Vena Cava.

History A 65-year-old woman presented to her primary care physician with a history of progressive abdominal pain mainly in the upper quadrants, nausea, and edema in the bilateral symmetric lower extremities. Other symptoms and use of medication or related drugs were denied. Physical examination findings were normal.

Do clinical and radiologic features help predict malignancy of B3 breast lesions without epithelial atypia (B3a)?

Objectives: To evaluate excision histology outcome of B3a lesions diagnosed at imaging-guided core biopsy and assess whether clinical and radiologic features may predict upgrade to malignancy.

Methods: A total of 153 B3a lesions (74 papillomas, 51 radial scars and 28 fibro-epithelial lesions) that underwent surgical excision were assessed. PPV for malignancy in all B3a lesions and specific for each sub-category was evaluated.

A comparison between 915 MHz and 2450 MHz microwave ablation systems for the treatment of small diameter lung metastases.

Purpose: We aimed to retrospectively compare the local tumor control rates between low frequency (LF) and high frequency (HF) microwave ablation devices in the treatment of <3 cm lung metastases.

Methods: A total of 36 patients (55 tumors) were treated with the LF system (915 MHz) and 30 patients (39 tumors) were treated with the HF system (2450 MHz) between January 2011 and March 2016. Computed tomography (CT) scans performed prior to and 24 hours after the ablation were used to measure the size of the ablation zone and to calculate the ablation margin.

Transarterial chemoembolization in pancreatic adenocarcinoma with liver metastases: MR-based tumor response evaluation, apparent diffusion coefficient (ADC) patterns, and survival rates.

Purpose: To retrospectively investigate the effectiveness of triple drug combination transarterial chemoembolization (TACE) on local tumor response and survival in patients with liver metastases from pancreatic cancer. Also, this study will evaluate the variances in response regarding the number of metastases, assess the correlation between tumor response and the changes in the apparent diffusion coefficients (ADC) in diffusion weighted (DW) MRI.

Materials And Methods: One hundred and twelve patients (58 men and 54 women; mean age 57) with malignant liver metastases from pancreatic adenocarcinoma underwent at least one session of TACE with a chemotherapeutic combination of mitomycin C, cisplatin, and gemcitabine.

Automated breast ultrasound: basic principles and emerging clinical applications.

Automated breast ultrasound (ABUS) is a recently introduced ultrasonography technique, developed with the purpose to standardize breast ultrasonography and overcome some limitations of handheld ultrasound (HHUS), such as operator dependence and the considerable amount of medical time necessary to perform and interpret HHUS. This new ultrasonography technique separates the moment of image acquisition (that may be performed also by a technician) from that of its interpretation, increasing reproducibility, reducing operator-dependence and physician time. Moreover, multiplanar reconstructions, especially the coronal view, introduce new diagnostic information.
