Breast MRI takes on CT in hepatic lesions and intraductal carcinoma

By Shalmali Pal

Two new studies have examined the role of MRI and CT in breast cancer and subsequent metastatic disease. Radiologists in New York City sought to find out whether MRI should be used to differentiate benign and malignant lesions in patients with indeterminate CT findings. And Japanese researchers pitted MRI against multidetector-row CT (MDCT) for determining the lesion margins for surgical removal. They found that one modality was superior to the other.

False negative for mammography resolved by tomosynthesis

This woman had her regular screening mammogram, which was rated as BI-RADS 1, or normal.

Some weeks later she returned because of a palpable lump in her breast. Ultrasound detected this lump and was determined through biopsy to be DCIS. Her mammogram was retrospectively reviewed and the cancer was deemed to be mammographically occult.

On review of the tomosynthesis image, taken at the same time as the mammogram, the cancer can be clearly seen near the skin line above the nipple.

This image is from a technology that is a work-in-progress and that does not have regulatory approval in certain global markets.

False positive for mammography resolved by tomosynthesis

An object on a conventional digital mammogram was highly suspicious for malignancy. The structure was seen in both the MLO and CC views, and persisted on the multiple diagnostic mammograms. The patient underwent biopsy and the structure was benign.

If you look at the corresponding tomosynthesis images, you see nothing malignant. The structure seen in the conventional mammogram was the result of overlapping tissues. Diagnosis was given as superimposed parenchyma.

At another height in the breast, a series of calcifications can be seen in the tomosynthesis cine loop. Because of the 3D nature of the tomosynthesis images, these are known to be within a few millimeters of the skin’s surface.

This image is from a technology that is a work-in-progress and that does not have regulatory approval in certain global markets.

Preop FDG-PET spots axillary involvement in breast cancer, may obviate biopsy

By Shalmali Pal

Surgeons should consider breast PET studies to determine if they can skip biopsy and proceed straight to axillary lymph node dissection (AND), according to a study in the Archives of Surgery. But the study authors cautioned that the PET exam must predict positive nodes with 100% specificity.
