The TI-RADS (Thyroid Imaging Reporting and Data Systems) are sonographic classification systems which describe the suspicious findings of thyroid nodules. [12] It was first proposed by Horvath et al., [13] based on the BI-RADS (Breast Imaging Reporting and Data System) concept. Several systems were subsequently proposed and adopted by ...
Some ultrasound results may report a TI-RADS or TIRADS score to categorize the risk of malignancy. [23] Measurement of thyroid stimulating hormone , free and/or total triiodothyronine (T3) and thyroxine (T4) levels, and antithyroid antibodies will help decide if a functional thyroid disease such as Hashimoto's thyroiditis is present, a known ...
Following this initiative the ACR, ESUR, and the AdMeTech Foundation formed a Joint Steering Committee, and by 2016 published a second version of PI-RADS (v.2) in European Urology. [4] This paper enabled acceptance of the urologists of prostate MRI and was awarded “Best clinical scientific paper of 2016 in European Urology”.
BI-RADS. The Breast Imaging-Reporting and Data System (BI-RADS) is a quality assurance tool originally designed for use with mammography. The system is a collaborative effort of many health groups but is published and trademarked by the American College of Radiology (ACR). The system is designed to standardize reporting and is used by medical ...
Radiation-induced cancer. Exposure to ionizing radiation is known to increase the future incidence of cancer, particularly leukemia. The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing ...
LIRADS classification is applied to multi-phase contrast-enhanced CT or MRI scans in people with certain chronic liver diseases. The Liver Imaging Reporting and Data System (aka LI-RADS) is a quality assurance tool created and trademarked by the American College of Radiology in 2011 to standardize the reporting and data collection of CT and MR ...
Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...
J ⋅ kg −1. Absorbed dose is a dose quantity which is the measure of the energy deposited in matter by ionizing radiation per unit mass. Absorbed dose is used in the calculation of dose uptake in living tissue in both radiation protection (reduction of harmful effects), and radiology (potential beneficial effects, for example in cancer ...
