IgG4-related disease mimicking gynecologic malignancy.

Immunoglobulin G4 (IgG4) related disease is a systemic disease that causes fibrosis, tumor-like nodules, and lymphoid hyperplasia with infiltration of IgG4 positive plasma cells. It can manifest in many organ systems; however, there are few cases that report gynecologic organ involvement. It is crucial to correctly diagnose IgG4-related disease versus malignancy because the former is treated with glucocorticoids or rituximab.

A Clinically Optimal Protocol for the Imaging of Enteric Tubes: On the Basis of Radiologist Interpreted Diagnostic Utility and Radiation Dose Reduction.

Rationale And Objectives: The purpose of this study was to develop and evaluate a patient thickness-based protocol specifically for the confirmation of enteric tube placements in bedside abdominal radiographs. Protocol techniques were set to maintain image quality while minimizing patient dose.

Materials And Methods: A total of 226 pre-intervention radiographs were obtained to serve as a baseline cohort for comparison.

Effect of Echo Times on Prostate Cancer Detection on T2-Weighted Images.

Purpose: To compare the effect of different echo times (TE) on the detection of prostate cancer (PCa) on T2-weighted MR images.

Materials And Methods: This study recruited patients (n = 38) with histologically confirmed PCa who underwent preoperative 3T MRI. Three radiologists independently marked region on interests (ROIs) on suspected PCa lesions on T2-weighted images at different TEs: 90, 150, and 180 ms obtained with Turbo Spin Echo imaging protocol with multiple echoes.

MR Imaging-Guided Focal Therapies of Prostate Cancer.

MR imaging-guided focal therapy is a viable treatment option for patients with localized prostate cancer. After the identification of a malignant focus in the prostate gland on multiparametric MR imaging, treatment can be directed in a precise fashion to the area of interest. The goal of focal therapy is to eradicate prostate cancer while minimizing complications that can affect quality of life.

Performance of T2 Maps in the Detection of Prostate Cancer.

Rationale And Objectives: This study compares the performance of T2 maps in the detection of prostate cancer (PCa) in comparison to T2-weighted (T2W) magnetic resonance images.

Materials And Methods: The prospective study was institutional review board approved. Consenting patients (n = 45) with histologic confirmed PCa underwent preoperative 3-T magnetic resonance imaging with or without endorectal coil.

Multiparametric MR Imaging of the Prostate after Treatment of Prostate Cancer.

The use of multiparametric magnetic resonance (MR) imaging in prostate cancer therapy is increasing, as newer treatment methods and management approaches emerge. The mainstays of therapy-radiation and surgery-are being supplemented (and even replaced) by novel focal therapy methods. Laser and ultrasonographic ablation, photodynamic therapy, electroporation, and cryoablation are the most common focal therapies, each with its own imaging findings.

Performance of Ultrafast DCE-MRI for Diagnosis of Prostate Cancer.

Rationale And Objectives: This study aimed to test high temporal resolution dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) for different zones of the prostate and evaluate its performance in the diagnosis of prostate cancer (PCa). Determine whether the addition of ultrafast DCE-MRI improves the performance of multiparametric MRI.

Materials And Methods: Patients (n = 20) with pathologically confirmed PCa underwent preoperative 3T MRI with T2-weighted, diffusion-weighted, and high temporal resolution (~2.

Thyroid Nodule Size at Ultrasound as a Predictor of Malignancy and Final Pathologic Size.

Background: Thyroid-related mortality has remained constant despite the increasing incidence of thyroid carcinoma. Most thyroid nodules are benign; therefore, ultrasound and fine needle aspiration (FNA) are integral in cancer screening. We hypothesize that increased nodule size at ultrasound does not predict malignancy and correlation between nodule size at ultrasound and pathologic exam is good.

MRI-guided focal therapy of prostate cancer.

With the advent of focal therapy as a recognized treatment option for men with prostate cancer, there are a host of emerging interventions that take advantage of MRI for image guidance. Focal therapy affords a middleground option for patients with low- to intermediate-grade prostate cancer by providing a means of keeping their cancer at bay while avoiding the negative consequences of radical therapies. However, the practice of focal treatment is far from straightforward, with some believing focal treatment errs on the side of overtreatment among patients with low-grade cancer; others worry it is undertreatment in potentially significant multifocal disease.

Surgical excision of benign papillomas diagnosed with core biopsy: a community hospital approach.

Our goal was to assess the value of surgical excision of benign papillomas of the breast diagnosed on percutaneous core biopsy by determining the frequency of upgrade to malignancies and high risk lesions on a final surgical pathology. We reviewed 67 patients who had biopsies yielding benign papilloma and underwent subsequent surgical excision. Surgical pathology of the excised lesions was compared with initial core biopsy pathology results.
