A bone marrow biopsy removes a small amount of bone and a small amount of fluid and cells from inside the bone (bone marrow). A bone marrow aspiration removes only the marrow. These tests are often done to find the reason for many blood disorders and may be used to find out if cancer or infection has spread to the bone marrow.
Bone marrow aspiration removes a small amount of bone marrow fluid and cells through a needle put into a bone. The bone marrow fluid and cells are checked for problems with any of the blood cells made in the bone marrow. Cells can be checked for chromosome problems. Cultures can also be done to look for infection.
A bone marrow biopsy removes bone with the marrow inside to look at under a microscope. The aspiration (taking fluid) is usually done first, and then the biopsy.
And thanks to my wonderful disagreable bones I get the pleasure of doing a CT guided biopsy with Procedural sedation. This is defined as "a technique of administering sedatives or dissociative agents with or without analgesics to induce a state that allows the patient to tolerate unpleasant procedures while maintaining cardiorespiratory function." It was previously referred to as conscious sedation"
Unfortunatly in about 1/2 the times the medications used do not work for me and I end up in severe pain and "grinning and baring it while they hammer that needle in.......as was today......
and so the wait beings, every cancer patients least favorite time.... the waits are torture.
