22
Q

What are the different Imaging Modalities?

A

Magnetic resonance imaging (MRI), computed tomography (CT) scan, positron emission tomography (PET) scan, Diagnostic ultrasound, Mammography, single-photon emission computerized tomography (SPECT) scan, Fluoroscopy, and X-ray

23
Q

a medical imaging procedure that creates detailed images of the body’s organs and tissues by using a magnetic field and computer-generated radio waves.

A

Magnetic resonance imaging (MRI)

24
Q

combines a sequence of X-ray images collected from various angles around the body and uses computer processing to create cross-sectional images of the bones, blood arteries, and soft tissues inside the body. contain more information than standard X-rays.

A

computed tomography (CT) scan

25
Q

a type of imaging examination that can reveal the metabolic or biochemical function of tissues and organs. employs a radioactive chemical known as a tracer to detect both normal and abnormal metabolic activity.

A

positron emission tomography (PET) scan

26
Q

often known as sonography or diagnostic medical sonography, is a type of imaging that employs sound waves to create images of structures within the body.

A

Diagnostic ultrasound

27
Q

x-ray imaging technique used to check the breast in order to detect cancer and other breast disorders early.

A

Mammography

28
Q

a type of nuclear imaging scan that combines computed tomography (CT) and a radioactive tracer. Doctors can examine how blood travels to tissues and organs due to the tracer. It may be utilized to aid in the diagnosis of seizures, strokes, and infections.

A

single-photon emission computerized tomography (SPECT) scan

29
Q

a medical imaging process that uses numerous pulses (short bursts) of an X-ray beam to display the internal organs and tissues on a computer screen in real time. Similar to a video

A

Fluoroscopy

30
Q

a rapid, painless diagnostic examination that generates images of the structures inside the human body, specifically the bones. Penetrates through the body and are absorbed in varying degrees depending on the density of the substance.
