Bone marrow imaging after suspending granulocyte colony-stimulating factor treatment. Bone marrow was slightly clear and slightly higher than the peripheral soft tissues; the silhouette was not clear, indicating mild to moderate bone marrow function inhibition. These findings correlate with level 1 of the standard bone marrow activity
