What is technetium 99m used for in medicine?

Tc-99m is the preferred tracer for a number of scans used in medicine worldwide to help diagnose medical conditions. Tc-99m scans are used to detect a wide range of conditions including injuries, infections, tumours, heart disease, thyroid abnormalities, kidney conditions and also to guide some cancer procedures.

Why technetium 99m is an effective isotope to use as a medical tracer?

Tc-99 m is ideal as a medical tracer because the gamma radiation it emits allows the medical practitioner to image internal body organs causing hardly any radiation damage to the patient.

Is technetium 99m injected?

Technetium Tc 99m oxidronate injection is a radiopharmaceutical. Radiopharmaceuticals are radioactive agents, which may be used to find and treat certain diseases or to study the function of the body’s organs.

What are uses for technetium?

The gamma-ray emitting technetium-99m (metastable) is widely used for medical diagnostic studies. Several chemical forms are used to image different parts of the body. Technetium is a remarkable corrosion inhibitor for steel, and adding very small amounts can provide excellent protection.

Why is 99mTc used in most cases?

Technetium-99m is a widely used radioactive tracer isotope in Nuclear Medicine. It’s gamma ray energy of about 140 keV is convenient for detection. The fact that both its physical half-life and its biological half-life are very short leads to very fast clearing from the body after an imaging process.

What radioisotope is used for bone scans?

Nuclear scintigraphy of the bone commonly utilizes the radionuclides technetium-99m (Tc-99m) or fluoride-18 (F-18). Tc-99m is usually attached to medronic acid (Tc-99m MDP), and F-18 is usually incorporated into sodium fluoride (F-18 NaF).

Are bone scans harmful?

A bone scan carries no greater risk than conventional X-rays. The tracers in the radioactive substance used in a bone scan produce very little radiation exposure. The risk of having an allergic reaction to the tracers is low. However, the test may be unsafe for pregnant or breastfeeding women.

What is the difference between a bone scan and a CT scan?

A CT scan is a high-resolution X-ray that gives detailed information about organ anatomy. A bone scan is a nuclear imaging test that aids in the diagnosis and tracking of several bone diseases. A CT scan uses a combination of X-rays and a computer to create images of the bones.

What does a bone scan show that a CT scan doesn t?

Bone scans can help diagnose several problems, including: Broken bones, especially hips, or stress fractures, which can be hard to see on X-rays. Arthritis. Paget’s disease of the bone, which affects how new tissue replaces the old.

Does a CT scan show bone?

A CT scan shows detailed images of different parts of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than standard X-rays.

How long does it take to get the results of a bone scan?

How soon will the scan results be available? A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.

Will a bone scan show disc problems?

Bone Scans Are Reliable for the Identification of Lumbar Disk and Facet Pathology.

Do you have to take your clothes off for a bone scan?

No special preparations are needed. You may be able to remain fully clothed, depending on the area of your body being scanned. But you’ll need to remove any clothes that have metal fasteners, such as zips, hooks or buckles. In some cases, you may need to wear a gown.

Does a bone scan show osteoporosis?

To diagnose osteoporosis and assess your risk of fracture and determine your need for treatment, your doctor will most likely order a bone density scan. This exam is used to measure bone mineral density (BMD). It is most commonly performed using dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry.
