Diagnostic imaging strategy for MDCT- or MRI-detected breast lesions: use of targeted sonography
نویسندگان
چکیده
BACKGROUND Leading-edge technology such as magnetic resonance imaging (MRI) or computed tomography (CT) often reveals mammographically and ultrasonographically occult lesions. MRI is a well-documented, effective tool to evaluate these lesions; however, the detection rate of targeted sonography varies for MRI detected lesions, and its significance is not well established in diagnostic strategy of MRI detected lesions. We assessed the utility of targeted sonography for multidetector-row CT (MDCT)- or MRI-detected lesions in practice. METHODS We retrospectively reviewed 695 patients with newly diagnosed breast cancer who were candidates for breast conserving surgery and underwent MDCT or MRI in our hospital between January 2004 and March 2011. Targeted sonography was performed in all MDCT- or MRI-detected lesions followed by imaging-guided biopsy. Patient background, histopathology features and the sizes of the lesions were compared among benign, malignant and follow-up groups. RESULTS Of the 695 patients, 61 lesions in 56 patients were detected by MDCT or MRI. The MDCT- or MRI-detected lesions were identified by targeted sonography in 58 out of 61 lesions (95.1%). Patients with pathological diagnoses were significantly older and more likely to be postmenopausal than the follow-up patients. Pathological diagnosis proved to be benign in 20 cases and malignant in 25. The remaining 16 lesions have been followed up.Lesion size and shape were not significantly different among the benign, malignant and follow-up groups. CONCLUSIONS Approximately 95% of MDCT- or MRI-detected lesions were identified by targeted sonography, and nearly half of these lesions were pathologically proven malignancies in this study. Targeted sonography is a useful modality for MDCT- or MRI-detected breast lesions.

The breast cancer is common in females.Early detection with safe , convenient , noninvasive and accessible diagnostic tools are important. X- ray mammography is still the first choice imaging for breast cancer, but has low specificity and limited value in dense breast and surgically scarred breasts. In recent years , MIBI scintimammography has been used for this purpose. The...

Background The performance of TVS, TRS and MRI for the diagnosis of DIE have been separately reported in earlier studies. However, the three methods have not been concurrently compared in terms of their overall performance and classified results as per different anatomical locations of DIE lesions in a large study population. This study was an attempt to compare pelvic magnetic resonance imagin...
متن کاملAdvanced MRI findings in patients with breast hamartomas.
PURPOSE Although it has been stated that breast hamartomas are rare tumors, radiologists frequently encounter them in their daily practices. Fat, glandular and fibrous tissues all produce a mass of disorganized but mature specialized cells. Because hamartomas do not have specific diagnostic histological features, the clinical and radiological findings are important in their diagnosis. The aim o...

Asymptomatic women who have received silicone injection for breast augmentation have a risk of underestimating breast cancer by palpation, mammography, or breast sonography. Enhanced breast MRI is sensitive to display certain nonspecific enhanced lesions or suspicious lesions. Such nonspecific MRI-detected lesions could be managed by American College Radiology BI-RADS lexicon and selectively wi...
