1.   Finally, computed tomography of the chest showed pleural thickening at the left lung base in an area corresponding to that previously noted on a chest x ray.

2.   Thirty four patients with inoperable oesophageal cancer were investigated by endosonography and computed tomography before medical treatment.

3.   These results suggest that endosonography is better than endoscopic biopsy specimens and computed tomography in assessing the response of oesophageal carcinoma to non-surgical treatment.

4.   A second evaluation was performed three months afterwards and included endoscopy, abdominal ultrasonography, and computed tomography.

5.   We therefore conclude the endoscopic ultrasound is better than endoscopic biopsy tissue and computed tomography in assessing correctly the response of oesophageal carcinoma to medical treatment.

6.   Baron et al compared the value of ultrasound and computed tomography in patients with suspected biliary obstruction.

7.   Osteonecrosis often begins insidiously and is difficult or impossible to diagnose with conventional radiography and computed tomography in the early stages.

8.   SPECT, or single-photon emission computed tomography, involves the use of a short-lived radioactive isotope that is injected into the patient.
