Background: Type 2 time-intensity curves can indicate both malignant and benign breast lesions in dynamic contrast enhanced magnetic resonance imaging (DCE-MRI).

Purpose: To investigate whether diffusion-weighted imaging (DWI) or early phase kinetics of DCE-MRI is practical to discriminate breast masses that depict type 2 curve in DCE-MRI.

Material And Methods: We retrospectively included 107 lesions in 97 patients with type 2 curves in DCE-MRI.

Determination of the acetabular morphology and orientation is important for the total hip arthroplasty applications. In general, preoperative planning for these patients is done on true hip X-rays in orthopedics clinics. But those evaluations may not represent the acetabular architecture in detail, because of 2 dimensional images.

Objective: The aim of this study was to evaluate the diagnostic performance of multiparametric magnetic resonance imaging for clinically significant prostate cancer and to determine whether applying Prostate Imaging Reporting and Data Systems version 2.1 score could improve the diagnostic pathway besides the biochemical characteristics.

Materials And Methods: In this study, 199 patients with clinically suspected prostate cancer who underwent multiparametric magnetic resonance imaging were included.

Purpose: To evaluate the diagnostic performance of pelvimetric measurements, in particular the pelvic dimension index (PDI)/prostate volume (PV) ratio (PDI/PV), in predicting positive surgical margin (PSM) in prostate cancer (PC).

Materials And Methods: 127 patients who had pre-operative pelvic imaging were included in this study. Demographic and clinical data were recorded.

Background: Image-guided breast biopsies are well accepted, yet stressful procedures for patients in radiology clinics.

Purpose: To investigate the effect of music on anxiety, pain, and patient satisfaction related to a breast biopsy session.

Material And Methods: After approval of institutional review board and giving informed consent, 93 women scheduled for ultrasound-guided breast biopsy or stereotactic wire localization were prospectively enrolled in this randomized controlled study.

Purpose: The aim of this study is to assess the utility of fasting on Doppler ultrasonography findings of hepatic artery in liver transplants.

Methods: Liver transplant patients without vascular abnormalities were prospectively evaluated between December 2017 and January 2020. Doppler sonography was used to describe hemodynamic changes in response to a standard meal.

Background/aim: Strain elastography has the disadvantage of being operator-dependent. Interobserver variability is observed during image acquisition and interpretation. This study aimed to analyze the interobserver and intermethod variability of strain elastography in image interpretation and evaluate the diagnostic performance combining elasticity score and strain ratio with ultrasonography.

Purpose: The aim of this study is to evaluate the diagnostic performance of combined breast magnetic resonance imaging (MRI) protocol including dynamic contrast-enhanced MRI (DCE-MRI) and diffusion-weighted imaging (DWI) in patients with enhancing lesions that demonstrated washout curve and to determine whether applying apparent diffusion coefficient (ADC) cutoff value could improve the diagnostic value of breast MRI.

Methods: The retrospective study included 116 patients with 116 suspicious breast lesions, which showed washout curve on DCE-MRI, who underwent subsequent biopsy. Morphologic characteristics on DCE-MRI and ADC values on DWI were evaluated.

Objective: The aim was to evaluate relationship between apparent diffusion coefficient (ADC) values with pathologic prognostic factors in breast carcinoma (BC).

Materials And Methods: 83 patients were enrolled in this study. Prognostic factors included age, tumor size, expression of estrogen receptor (ER) and progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), nuclear grade (NG), lymph node involvement and histologic type.

Objectives: The hepatic vasculature is a unique system due to a dual supply that includes the hepatic artery and portal vein, which interact when the liver vascular supply is decreased. Hepatic artery buffer response, an intrinsic regulatory mechanism that compensates for blood supply, maintains increased hepatic artery flow and caliber in response to portal vein failure. Previous studies revealed that portal vein flow showed no alterations to establish adequate blood supply in response to hepatic artery occlusion.

Objectives: Although biopsy is the most important method for diagnosing the cause of renal allograft dysfunction, sonoelastography, a new ultrasonography method, can be used to distinguish between the soft or hard nature of lesions. In this study, our aim was to investigate whether sonoelastography could diagnose fibrosis in renal transplant patients.

Materials And Methods: In this prospective study, we included patients over 18 years old who were recommended for clinical biopsy.

Objectives: To evaluate the efficacy of low-level laser therapy on median nerve stiffness by using strain elastography in carpal tunnel syndrome (CTS).

Methods: This study included 37 wrists of 34 patients with mild or moderate CTS between January 2016 and August 2016. The control group comprised 17 patients (18 wrists) with CTS who were treated with wrist splinting for 3 weeks.

A 47-year-old male patient underwent living-related renal transplant. On day 3 posttransplant, without evidence of associated clinical symptoms, the patient's serum creatinine levels had increased. The patient was given immunosuppressive medication, and a followup Doppler ultrasonography revealed hypoechoic areas in the inferior pole of the renal parenchyma.

Purpose: To investigate whether a novel method that combines breast imaging reporting and data system (BI-RADS) with strain elastography contributes to diagnostic performance in differentiation of malignant and benign breast lesions.

Methods: In 81 patients, 81 breast lesions were prospectively investigated. Breast lesions were separately evaluated with ultrasonography and strain elastography.
