Contrast-enhanced in-phase Dixon sequence impacts biopsy clip detection on breast MRI

Mammographers have long used contrast-enhanced in-phase Dixon sequence MRI to improve the conspicuity of breast lesions. This technique relies on the different properties of water and fat to produce images with high contrast between these tissues. However, a new study has found that this technique may actually reduce the detection of biopsy clips on MRI.

Researchers examined the records of 449 women who had undergone breast MRI. Of these, 52 had biopsy clips placed at the time of their MRI. The researchers found that contrast-enhanced in-phase Dixon sequence MRI was associated with a significantly reduced clip detection rate.

The authors believe that the contrast between water and fat may obscure the clips, making them more difficult to detect. They recommend that clinicians be aware of this potential issue when interpreting breast MRI.

This study highlights the importance of using multiple imaging techniques when evaluating breast lesions. MRI is an important tool in the diagnosis of breast cancer, but it should not be used in isolation. When using contrast-enhanced in-phase Dixon sequence MRI, clinicians should be aware of the potential for reduced clip detection and consider using alternative imaging sequences.

Contrast-enhanced imaging is the mainstay of breast MRI. However, the impact of contrast-enhanced in-phase Dixon sequence on biopsy clip detection has not been well studied. The purpose of this study was to assess the impact of contrast-enhanced in-phase Dixon sequence on biopsy clip detection on breast MRI.

A total of 100 breast MRI exams were retrospectively reviewed. All exams were performed on a 3.0T scanner using a dedicated breast coil. Fifty cases were randomly selected for in-phase Dixon imaging and the other fifty cases were included as a control group. All cases were interpreted by two experienced breast radiologists who were blinded to the purpose of the study.

The in-phase Dixon images were found to have better contrast compared to the control images (p < 0.001). There was no significant difference in the number of biopsy clips detected between the two groups (p = 0.39). The findings of this study suggest that contrast-enhanced in-phase Dixon imaging does not impact biopsy clip detection on breast MRI. This study provides valuable information for institutions considering the implementation of in-phase Dixon imaging for breast MRI.
