- “ The introduction of spiral computed tomography from the days of single-slice spiral to today's 64-row multidetector computed tomography and beyond creates datasets with unprecedented spatial and temporal resolution. The key to computed tomography imaging in the big picture is not in the acquisition of data, but in the use of the data acquired. By supplementing traditional axial interpretation with 3-dimensional rendering of the computed tomography volume, the greatest amount of information available is extracted. The information provided by a comprehensive postprocessed study, which includes multiplanar reconstruction in the coronal, sagittal, and oblique plane, as well as 3-dimensional maps of both the arterial and venous phase datasets using volume rendering and maximum intensity projection techniques, allows for key clinical decisions to be made with a high degree of accuracy. Postprocessing of computed tomography data is thus no longer an option, but a true requirement in this era of 64-row multidetector computed tomography and beyond.”

- Common Misdiagnosis in Body CT: Solutions
- The need to be aware of pitfalls in general helps you avoid those pitfalls
- Moving to routine review of non-axial plane imaging. Even a cursory look at coronal and sagittal images will be useful
- New workflow patterns with next generation workflow and software that incorporate “advanced visualization tools” and make them “standard visualization tools”. - Common Misdiagnosis in Body CT Unsuspected pulmonary embolism
- Gastric tumors especially toward the fundus
- Etiology of biliary tract obstruction (stone)
- Pancreatic tumor detection
- Renal tumors especially in the upper/lower pole
- Small bowel tumor detection
- Mesenteric vascular pathology
- Musculoskeletal pathology "At some point, multiplanar reconstructions will become the standard of care, as opposed to a supplemental display technique."
MDCT of the Abdomen: Common Misdiagnosis at a Busy Academic Center

AJR 2010; 194:660-667- "At our busy academic institution, we have noticed repeated examples of certain misdiagnosis, even by experienced abdominal imagers, both in our own department and at outside institutions. This is likely related to many factors. Discussed here are a variety of common diagnostic errors on body CT examinations."
