Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

What will a gallium scan show that an MRI doesn't?

More function: Mri is more anatomic in detecting configuration of soft tissues and extent of disease. Sometimes not able to entirely differentiate infection from tumor or infarction of bone. Gallium may be used sometimes to detect infection. However not specific accumulating in infection, some tumors, and inflammatory conditions. Nuclear tagged white blood cells are usually more specific for infection. ...Read more

I have a history of osteomylitis and it showed up on gallium scan before, why did my doctor order a bone scan?

I have a history of osteomylitis and it showed up on gallium scan before, why did my doctor order a bone scan?

Ask your doctor: Gallium is sometimes used to detect active or chronic infection. Gallium not specific can have uptake in tumors and trauma. It does not tell much about healing of bone. Bone scan is more specific for bone metabolism including infection fracture, repair. The degree of uptake usually determines activity of process. Lot of people use tagged white blood cells for detecting infection, more specific. ...Read more

Can you tell me if gallium scans detect chronic infections?

Can you tell me if gallium scans detect chronic infections?

Yes: Gallium scans are very good for detecting chronic infections or any chronic inflammatory process, often better than acute infections. Some infections they can be used to identify are pcp pneumonia or osteomyelitis of the spine. They are not very good for intra-abdominal infections or inflammation since the normal clearance of gallium through the gut may cause false positive result. ...Read more

How do they do a lung VQ scan on a person?

Two steps procedure: A lung scintigraphy has two components. The ventilation part (v of v/q) which consists in inhalation of 99mtc-gaz or aerosols and the perfusion part ( q of v/q) which involves the intravenous injection of 99mtc-maa which are used to see the perfusion of the lungs. Usually a lung scan is performed to detect pulmonary emboli ( blood clots in the lungs) or to perform a preoperative evaluation ...Read more

Inject radioactive: A perfusion lung scan is done by injectecting a low-dose radioactive tracer into a vein and taking images showing where blood flow is going in the lungs. It is used to diagnose pulmonary embolism (blood clot to the lungs). The test is safe and generally free of any side effects. It is used less often now than ct angiogram, but is safer and involves less radiation exposure. ...Read more

From a CAT scan: what does "Thymic gland tissue IN lungs" mean?

It may be: just a poorly worded sentence.The thymus gland is not located in the lung, although it is in the thoracic cavity(anterior mediastinum). Residual thymic tissue in the mediastinum is normal at your age. An invasive thymic malignancy could involve the lungs, but otherwise it is impossible to have thymic tissue in the lungs, and even if it was, CT wouldnt be able to tell what it is. ...Read more
