Computed tomographic scanning in patients with lymphoma.

|February 1, 1978
Summary
Computed tomography (CT) scans accurately detect lymphoma in 85% of cases, offering valuable insights for staging and evaluation. This imaging technique shows high agreement with lymphography, particularly for abdominal lymph node involvement.
Area of Science:
- Radiology
- Oncology
Background:
- Lymphoma diagnosis and staging are critical for effective treatment planning.
- Conventional diagnostic techniques have limitations in visualizing certain lymphomatous involvements.
Purpose of the Study:
- To evaluate the diagnostic accuracy of computed tomography (CT) of the chest and abdomen in patients with lymphoma.
- To compare CT findings with conventional diagnostic methods.
Main Methods:
- Computed tomography (CT) scans of the chest and abdomen were performed on 40 patients diagnosed with lymphoma.
- CT results were compared against findings from conventional diagnostic techniques, including lymphography.
Main Results:
- CT scans correctly identified the presence or absence of lymphoma in 34 out of 40 patients (85% accuracy).
- A high degree of agreement was observed between CT and lymphography findings in 26 out of 27 cases.
- CT demonstrated particular utility in assessing lymphomatous involvement of mesenteric lymph nodes, high retroperitoneal lymph nodes, and extranodal abdominal sites (pancreas, kidney).
Conclusions:
- Abdominal CT is a valuable noninvasive diagnostic tool for the initial staging of lymphoma.
- CT facilitates the subsequent evaluation of selected lymphoma patients, especially for extranodal disease.
