I this is an example of a common nuclear medicine test is called a bone scan a radioisotope is injected I and in this case the projections are acquired after the injection this bright spot here is where the injection occurred so there's a lot of tracer that just happen to you extravasations the tissues and the rest the tracer went into the bones and is useful in looking for I'm a task the season the bone looking at disseminated I'm bone disease it very quickly screams the whole body I this is another example this is just as white on black a eggs are safe white yeah the black and white image user couple a rib fractures for example bone scans highlight anywhere where there's what's called osteoblastic activity that's where newborn bonus for me here's an example a patient with extensive prostate cancer this is a radiograph these are the distribution of the areas where the bone is trying to regenerate in the in the sites where the prostate cancer has distributed into the bones so this is a common application for bone scanning and PET scanners more and more are being combined with CT scanners because where's the PET scanner gives use lot information about tissue function it doesn't really show us the anatomy well the CT shows us the anatomy well sphere’s a pen image with a really bright our object this Isa place that is a lot of Diabacor concentration tracer here's theft scan when you put it together the lung cancer that we see here is taking up a lot up the tracer and the tracer here is going to be fluorodeoxyglucose which is the primary I A tracer that is used for pat glucose metabolism is very important in cancer metabolism and so cancer loves glucose and so we used at the FTGfluorodeoxyglucose is the Floor F 18 that is the positron emitter and that that is attached the glucose and enables us to see this another example a PET scanning this is patient with Hodgkin's lymphoma.
