Summary
A new Thyroid Imaging Reporting and Data System (TIRADS) effectively categorizes thyroid nodules and assesses malignancy risk. This practical system achieved 97% accuracy in distinguishing benign from malignant nodules.
Area of Science:
- Radiology
- Oncology
- Endocrinology
Background:
- Thyroid Imaging Reporting and Data System (TIRADS) is used for thyroid nodule risk stratification.
- Current TIRADS versions lack clinical consensus for reporting ultrasound results.
- A need exists for a practical TIRADS to categorize nodules and assess malignancy risk.
Purpose of the Study:
- To develop a practical TIRADS for thyroid nodule categorization and malignancy risk stratification.
- To create a scoring system based on specific ultrasound features.
Main Methods:
- A novel TIRADS scoring system was developed using ultrasound features: calcification shape, margins, taller-than-wide, internal echo, and blood flow.
- Weights were assigned, and a score was calculated.
- The developed TIRADS was validated against existing TIRADS versions and radiologist assessments in 153 patients undergoing US-guided fine-needle aspiration biopsy.
Main Results:
- The novel TIRADS demonstrated 97% overall accuracy (100% malignant, 95% benign) in 153 cases.
- Malignancy rates for the new TIRADS categories were: TIRADS 2 (0%), TIRADS 3 (3.6%), TIRADS 4 (17-75%), and TIRADS 5 (98%).
Conclusions:
- A novel TIRADS was established using six ultrasound features and a scoring system.
- This system provides standardized vocabulary, a quantifiable score, and risk assessment for thyroid nodules.
- The objective, quantitative classification by this TIRADS aids in guiding clinical management decisions.

Force Classification
2.4K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

Classification of Neurotransmitters
5.3K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Classification of Leukocytes
6.0K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Classification of Illness
8.8K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Classification of Bones
10.0K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Seizures: Classification
1.7K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
