Computed tomography in 101 patients with a palpable abdominal mass
Clinical Radiology
|July 1, 1984
Summary
Computed tomography (CT) accurately detects abdominal masses. This imaging technique has high predictive values, confirming its value in diagnosing palpable or suspected masses of unknown origin.
Area of Science:
- Radiology
- Medical Imaging
- Abdominal Diagnostics
Background:
- Palpable or suspected abdominal masses present diagnostic challenges.
- Determining the presence and origin of abdominal masses is crucial for patient management.
Purpose of the Study:
- To evaluate the diagnostic accuracy of computed tomography (CT) for abdominal masses.
- To assess the positive and negative predictive values of CT in this context.
Main Methods:
- A prospective study involving 101 patients with palpable or suspected abdominal masses.
- All patients underwent computed tomography (CT) examination.
Main Results:
- CT demonstrated an abnormality in 69 patients, with a 99% positive predictive value (1 false positive).
- CT showed no lesion in 32 patients, with a 97% negative predictive value (1 false negative).
- CT correctly identified the responsible organ in 93% and suggested the likely nature of the mass in 88% of cases with lesions.
Conclusions:
- Computed tomography (CT) is highly valuable in confirming or excluding abdominal masses.
- CT effectively determines the presence, absence, and origin of clinically apparent abdominal masses.
