Fetal imaging
By Manuel Recio Rodríguez, MD, Associate Chief of Diagnostic Imaging Department
With the AIR Technology™‡ Anterior Array (AA), we can achieve good signal penetration for fetal imaging. This enables us to obtain high-quality images of the fetal brain with short acquisition times using T2 and DWI sequences.

AIR Technology™ AA provides excellent signal penetration for high-quality images. (A) Sagittal T2 SSFSE; (B) Coronal T2 SSFSE; (C) Axial T2 SSFSE; and (D) Axial DWI b800.
Abdominal imaging
By Vicente Martinez de Vega, MD, Chief of Diagnostic Imaging Department
Abdominal imaging with the AIR Technology™ Coils is better than we expected, particularly the coverage, signal homogeneity, high spatial resolution and scanning speed. We were also able to achieve short acquisition times and homogenous fat suppression. In this particular case, a thickening of the terminal ileum can be noticed in a very short segment, which is consistent with Crohn’s disease.

AIR Technology™ AA and PA Coils for abdominal imaging deliver better than expected coverage, signal homogeneity, high spatial resolution and homogeneous fat suppression. A thickening of the terminal ileum (red arrows) is consistent with Crohn’s disease.

Prostate imaging
By Manuel Recio Rodríguez, MD, Associate Chief of Diagnostic Imaging Department
Prostate MR is growing in use and referrals in our institution. However, in order to clearly depict the cancer to determine the extent of disease, it is necessary to obtain T2 sequences with high spatial resolution. Also, T2 Cube images can be used to merge with ultrasound to assist in performing targeted biopsies. In this particular case, a lesion with high signal in the T2-weighted sequence in the central prostate can be seen. There is no enhancement in the dynamic sequence and restricted diffusion is consistent with a prostate abscess. Dynamic acquisition with DISCO LAVA provides high spatial and temporal resolution (4.5 seconds per phase) and the diffusion imaging is very high quality.
Figure 5.
AIR Technology™ AA and PA provide high spatial resolution in T2 sequences, which improves visualization of the cancerous lesion for staging. Note the lesion with a high signal in the central prostate. (A) Axial T2 and (B) Axial T2 Cube.
