Electrocardiogram (ECG) is a test that measures the electrical activity of the heart, while the other options are all types of medical imaging technologies that produce images of the inside of the body.

X-ray is a type of medical imaging technology that uses X-rays to produce images of the inside of the body.

Ultrasound is a type of medical imaging technology that uses sound waves to produce images of the inside of the body.

Magnetic Resonance Imaging (MRI) is a type of medical imaging technology that uses magnetic fields and radio waves to produce images of the inside of the body.

Computed Tomography (CT) Scan is a type of medical imaging technology that uses X-rays and a rotating gantry to produce cross-sectional images of the inside of the body.

X-ray imaging technology offers high resolution images, is a non-invasive procedure, and is relatively low cost compared to other medical imaging technologies.

Ultrasound is commonly used to visualize blood flow and detect blood clots due to its ability to produce real-time images of the inside of the body.

MRI technology offers better soft tissue contrast, does not involve ionizing radiation, and can produce higher resolution images compared to CT scans.

X-ray is primarily used for diagnosing and monitoring bone and joint disorders due to its ability to provide clear images of bones and joints.

CT scans have several limitations, including high cost, exposure to ionizing radiation, and relatively long scan times compared to other medical imaging technologies.

Ultrasound is commonly used to guide minimally invasive procedures due to its ability to provide real-time images of the inside of the body.

PET scans offer the primary advantage of being able to detect metabolic activity in the body, which is useful for diagnosing and monitoring certain diseases.

Echocardiography is a type of medical imaging technology that uses ultrasound to produce images of the heart.

Nuclear medicine imaging techniques offer the primary advantage of being able to track the movement of substances in the body, which is useful for diagnosing and monitoring certain diseases.

Chest X-ray is a type of medical imaging technology that uses X-rays to produce images of the chest, including the lungs.
