Summary
Spiral CT effectively diagnoses breast lesions, accurately identifying invasive carcinomas and most benign conditions. This imaging technique offers valuable supplementary information beyond mammography and sonography for breast cancer diagnosis.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Mammography and sonography can present limitations in diagnosing breast lesions.
- Accurate characterization of breast lesions is crucial for timely and effective treatment.
Purpose of the Study:
- To evaluate the diagnostic utility of spiral computed tomography (CT) for breast lesions.
- To compare the efficacy of spiral CT with conventional imaging methods.
Main Methods:
- Spiral CT scans were performed on 93 female patients with suspicious mammographic findings.
- Scans included pre- and post-contrast enhancement with detailed parameters (e.g., 6 mm slice thickness, 4 mm increment, 200 ml contrast).
- Histological confirmation was obtained for 85 patients.
Main Results:
- Spiral CT accurately identified all 44 invasive carcinomas, characterized by intense contrast uptake.
- 36 of 38 benign lesions were correctly diagnosed; 2 fibroadenomas were misdiagnosed due to enhancement.
- The modality provided valuable additional diagnostic information compared to mammography and sonography.
Conclusions:
- Spiral CT is a highly useful tool for clarifying breast lesion diagnoses.
- Advantages include speed, patient comfort, minimal artifacts, standardization, and broad applicability in breast imaging.
