Routine pre- and post-hematopoietic stem cell transplant computed tomography of the abdomen for detecting invasive XXXX has limited value.

@entity1 @entity364
The diagnostic utility of obtaining chest and abdomen computed tomography (CT) to evaluate for invasive @entity364 (IFI) before and after hematopoietic stem cell transplant (HSCT) remains unclear. The study was conducted as a quality improvement project. Chest and abdomen CT of @entity1 who underwent an allogeneic HSCT over a 13-month period were reviewed. Scans included those performed pretransplant in all @entity1 and days 0 to 100 post-transplant in selected @entity1 . Sixty-six @entity1 had chest and abdomen CT scans pretransplant. Chest CT was suggestive of IFI in 9 @entity1 (13.6%), including 3 @entity1 with prior history of IFI. After transplant, 37 @entity1 had an initial chest CT and 14 @entity1 an initial abdominal CT. The first chest CT post-transplant was suggestive of IFI in 3 @entity1 ; all had an abnormal CT pretransplant. After the initial post-transplant evaluation, 15 @entity1 had 28 additional CT scans of the chest and 12 @entity1 19 additional CT scans of the abdomen. An abnormal chest CT with proven evidence of IFI was seen in only 1 @entity1 . None of the 99 abdominal CT scans performed pre- or post-transplant had evidence of IFI. There is little benefit in obtaining abdominal CT scans in HSCT @entity1 for detecting IFI either pre- or post-transplant.
