Cholangiography is a medical imaging test used to image the bile ducts in the liver and pancreas. It requires specialized knowledge and expertise to be performed safely and effectively. The test involves injecting a contrast dye into the bile ducts and using X-rays or other imaging modalities to create detailed images of the ducts. This technique is used to diagnose various conditions affecting the bile ducts, such as gallstones, tumors, and infections. Due to its complexity, cholangiography is typically performed by highly trained radiologists and interventional radiology specialists.

Drip Irrigation Machinery (DRTS) refers to a system designed for the efficient delivery of water and nutrients directly to the root zone of plants through a network of tubing and emitters. This skill involves understanding the components, installation, and maintenance of drip irrigation systems to optimize water usage and enhance crop yield. Knowledge of Drip Irrigation Machinery (DRTS) is utilized to manage irrigation schedules, monitor soil moisture levels, and reduce water waste in agricultural practices.

Radiobiology refers to the study of the effects of ionizing radiation on living organisms, including the mechanisms of radiation interaction with biological systems. This skill encompasses understanding cellular responses, DNA damage, and the biological consequences of radiation exposure. Knowledge of Radiobiology is used to inform safety protocols in medical imaging, radiation therapy, and nuclear industry practices, as well as to assess risks associated with radiation exposure in various environments.

Thyroid refers to knowledge of the structure, function, and common disorders of the thyroid gland. This skill is applied in clinical settings to assess symptoms, interpret test results, and support diagnosis and treatment planning for hormone related conditions. The skill also supports monitoring of response to care and appropriate follow up.

Transthoracic Echocardiogram refers to a non-invasive imaging technique that uses ultrasound waves to create detailed images of the heart's structure and function. This skill involves the application of ultrasound technology to assess cardiac chambers, valves, and blood flow, enabling the evaluation of various heart conditions. Knowledge of Transthoracic Echocardiogram is utilized in clinical settings to aid in diagnosis, monitor heart disease progression, and guide treatment decisions.
