MR-Guided Microwave Ablation in T1 Renal Cell Carcinoma: Initial Results in Clinical Routine

Figure 2

The procedure of treatment of a 54-year-old male patient with T1 renal cell carcinoma. When the patient uses T2 rapid (HASTE, 16 s) and T1 (VIBE, 16 s) sequences supine scans, it is found that the tumor is located on the right side of the body ((a) red arrow, (b) dashed circle). The lateral ablation angle cannot be implemented in the closed MRI modality, so the patient’s position needs to be adjusted to find the best ablation path. Adjust the patient’s body position to the oblique position ((c, d) red arrow), precisely insert the applicator into the target lesion position under the guidance of the continuous T1 (VIBE, 16 s) sequence, and ablate the lesion in the transverse position (e, f). The MWA-induced damage zone estimated as hyperintensity on T1 high signal range completely covers the tumor after during ablation ((g, h); red arrow).
