Scans designed to show the integrity of silicone implants

This ExamCard is designed for imaging of silicone implants using either the SENSE Body coil and the Breast Imaging device or the 7-channel MRI Devices Breast coil. SENSE and CLEAR are used to give visualization of the whole breast including axillae with improved speed and resolution.

ExamCard Image steps

sT2_TSE A T2 weighted sequence allowing visualisation of fluid around the implant and breast using SENSE for increased resolution in a short scan time.Silicone Only This sequence is designed to suppress all tissues except silicone. This is achieved by using STIR fat suppression and SPAIR water suppression.

This sequence is designed to suppress all tissues except silicone. This is achieved by using STIR fat suppression and SPAIR water suppression.
Silicone Suppressed This sequence is designed to suppress the signal from the silicone. It is based on the THRIVE technique with the SPAIR delay time lengthened to give the desired suppression. The delay time will vary for different types of Silicone implants and may need to be changed to give the desired results.THRIVE HR A high resolution 3D fat suppressed scan using SPAIR fat suppression.

Patient preparation

The patient should be prepared for the examination using the normal safety guidelines and screened for any contra-indications.

 

The patient is then positioned prone on the coil with both breasts positioned within the coil. The patient should be made as comfortable as possible and should be allowed to choose if they prefer their arms by their side or above their heads. Pads can be used to help to immobilize the breasts as long as no compression occurs. Patient comfort helps reduce motion artifacts which can greatly reduce image quality.

 

If a contrast injection is required in addition as part of a tumour study then the cannula should be inserted prior to positioning the patient.

Contrast agent / injection protocol

If a dynamic study is required then a dynamic scan can be used from the ExamCard Breast tumor.

Post-processing / analysis:

If required MPR/MIP projections can be obtained from the Silicone Only, Silicone Suppressed and THRIVE HR scans to allow more complete visualization of the implant.
