Instruments used in radiology
From Wikipedia the free encyclopedia
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 |
| Magnetic resonance imaging (MRI) alias Nuclear magnetic resonance (NMR) | high strength (0.15 to 1.5 teslas)[4] are used to excite protons that produce the record results (like CT scan). It can show particular tissues more clearly than CT.;[4] 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 |
