Difference Between Bone Marrow Biopsy and Bone Marrow Aspirate

Bone marrow biopsy:

Bone marrow biopsy for short, is to use a special puncture needle to take a small piece of cylindrical bone marrow tissue about 0.5 to 1 cm long for pathological examination. The operation method is exactly the same as that of bone marrow puncture, and the material taken out maintains the complete bone marrow tissue structure, which can make up for the deficiency of bone marrow puncture.

Bone marrow biopsy:

Bone puncture is the extraction of a small amount of bone marrow for examination. Bone marrow fills the bone marrow cavity and the cancellous reticulum of the bones, and is divided into two types: red bone marrow and yellow bone marrow. Red bone marrow has hematopoietic function, and yellow bone marrow has a lot of adipose tissue. With age, the red marrow in the medullary cavity is gradually replaced by the yellow marrow. Red bone marrow is retained in the spinal canal, sternum, ribs, clavicle, scapula, ilium, skull, and the cancellous material at the upper end of the femur and humerus. It is the main hematopoietic organ of the human body. The abnormal quality and quantity of blood cells is an important pathological change in hematological diseases. .
