| Kay, 2000 | 1 radiologist | Blinded to the results of colonoscopy and prior imaging | Radiologist interested in abdominal radiology Endoscopist experienced |
First 20 patients Next 18 patients |
60 35 |
| Macari, 2000 | 2 radiologists | Blinded to the results of colonoscopy Independently examined CTC data sets with Method 1 or 2 Method 1: Observer examined the axial and prone 2-D data sets in a cine mode and 3-D was used only as a problem solver. Method 2: Method 1 plus data was then completely examined using navigator software for simultaneous review of 3-D fly-through, coronal, sagital multiplanar reformatted, axial images. |
Radiologists had training and experience in the interpretation of CTC | Method 1 3-D rendering was used in 62% of patients |
