| Purpose: The purpose of this study was to assess the added value of screening
low-dose computed tomography of the chest (LDCT) covering the abdomen in evaluating
abdominal solid organs to the screening abdominal ultrasonography (US).
Materials and Methods: We prospectively enrolled a consecutive series of 393
physical check-up patients, who underwent screening abdominal US and LDCT of the
chest from January to February, 2008. LDCT covered the lungs, liver, pancreas, gallbladder,
spleen, and both kidneys. The 1st screening abdominal US were performed
without information from the LDCT, and then abdominal images covered by LDCT
were immediately evaluated. Then a 2nd US session was done with additional information
from LDCT and US examination was focused to the findings of LDCT. Perpatient
and per-lesion analyses were performed.
Results: In per-patient analysis, additional focal lesions were found in 20 patients
(5.1%) for liver and 9 patients (2.3%) for kidneys in the 2nd US sessions. In per-lesion
analysis, 154 and 73 focal lesions were found in liver and kidneys, respectively, in the
1st US sessions. On the 2nd US session, 186 and 86 lesions were found in liver and
kidneys, respectively. 20.8% and 17.8% of focal lesions were additionally found on
2nd US session in liver and kidneys, respectively. Most (62.5%) of the additional
lesions detected in liver were located in segment 7 and 8, the hepatic dome.
Conclusion: Previewing LDCT of the chest and abdominal solid organs before performing
screening abdominal US can enhance the diagnostic performance of US in
physical check-up patients. |
