Instruments used in radiology

Instruments used specially in radiology are as follows:[1][2][3]

Instrument | Uses

|

Ultrasonography machine | uses ultrasound to produce images from within the body; video link
X-ray | uses X-rays to produce images of structures within the body; video link
Contrast media for X-rays | to provide a high contrast image of the details of the viscera under study; e.g. salts of heavy metals, gas like air, radio-opaque dyes, organic iodides, etc.
Echocardiography machine | sonography of the heart is done here to know its function and state
Computer axial tomography scan (CT Scan)/(CAT Scan) | to visualize the interior of the body in slices (traditionally showing horizontal slices); video link
Linear accelerator | used in radiotherapy for cancer
Functional magnetic resonance imaging (fMRI) | video link
Positron emission tomography (PET Scan) | video link
Radio-isotope scan or nuclear scintigraphy | These radioactive compounds are administered so that specific tissues take them up. The amount and anatomical detail of the uptake produces the scan result.
SPECT scan | video link
Interventional radiology | minimally invasive surgeries under radiological imaging, e.g. angioplasty, TIPS.
Brachytherapy apparatus | video link
Lead shielding | visual and physical protection from x-ray
