Diagnostic value of ultrasound-guided fine needle aspiration biopsy in malignant thyroid nodules: utility for micronodules.
BACKGROUND The diagnostic approach to thyroid nodules involves ultrasound-guided fine needle aspiration biopsy (US-FNAB).We especially aimed to evaluate the contribution and the place of US-FNAB in preoperative evaluation of the malignant cases and draw attention to discordant cases diagnosed with papillary thyroid microcarcinoma (PTMC). MATERIALS AND METHODS A total of 276 cases were retrosp...
متن کاملAssessment of diagnostic value of DWI technique in the evaluation of liver fibrosis
Introduction: The liver fibrosis is caused by extracellular accumulation of cluster, glycos amino glycans and proteoglycans, which this extracellular accumulation may limit the penetration and molecular movement of water in the tissue, so the Diffusion weighted imaging(DWI) technique is due to the sensitivity to the movement and release of water molecules Can show this restrict...
متن کاملDWI of Prostate Cancer: Optimal b-Value in Clinical Practice
Aim. To compare the diagnostic performance of diffusion weighted imaging (DWI) using b-values of 1000 s/mm(2) and 2000 s/mm(2) at 3 Tesla (T) for the evaluation of clinically significant prostate cancer. Matherials and Methods. Seventy-eight prostate cancer patients underwent a 3T MRI scan followed by radical prostatectomy. DWI was performed using b-values of 0, 1000, and 2000 s/mm(2) and quali...
متن کاملComparison between ultra-high and conventional mono b-value DWI for preoperative glioma grading
To compare the efficacy of ultra-high and conventional mono-b-value DWI for glioma grading, in 109 pathologically confirmed glioma patients, ultra-high apparent diffusion coefficient (ADCuh)was calculated using a tri-exponential mode, distributed diffusion coefficients (DDCs) and α values were calculated using a stretched-exponential model, and conventional ADC values were calculated using a mo...
متن کاملSignal Intensity of High B-value Diffusion-weighted Imaging for the Detection of Prostate Cancer
Background: Diffusion-weighted imaging (DWI) is a main component of multiparametric MRI for prostate cancer detection. Recently, high b value DWI has gained more attention because of its capability for tumor characterization. Objective: To assess based on histopathological findings of transrectal ultrasound (TRUS)-guided prostate biopsy as a reference, an...
