“…In this study, the average duration was 134.1 min in liver biopsies, whereas soft-tissue biopsies lasted 73.0 min on 3 min using a 3T-system [17]. The time for the MR-guided biopsies also exceeded the procedure time of comparable CT-guided biopsies [21].…”

“…However, major disadvantages of magnetic resonance imaging (MRI) as a guiding technique are the high costs for a specialised interventional MRI-system or MRI-compatible biopsy-systems and the expected high time consumption accompanied with a loss of valuable MRI suite occupation time. Several publications have addressed the value of MRI-guided biopsy in liver and musculoskeletal lesions and in some publications the total duration of the interventions were stated [16,17]. Attempts to reduce the intervention time in using MR-fluoroscopic guidance [18] have been reported, however only one publication has focused on factors that affect the duration of MR-guided breast biopsies [19].…”

“…Stattaus et al [22] reported a sensitivity of 95.5%, specificity of 100%, and an accuracy of 96% using a short, wide-bore 1.5 T MR system. Kühn et al [23] reported an accuracy of 94%. Both groups agree that MR-guided procedures are also feasible for lesions with quite a steep angulation due to MRI’s capacity for multiplanar viewing.…”

ObjectiveTo determine whether 3D cone-beam computed tomography (CBCT) guidance allows safe and accurate biopsy of suspected small renal masses (SRM), especially in hard-to-reach anatomical locations.Materials and methodsCBCT guidance was used to perform 41 stereotactic biopsy procedures of lesions that were inaccessible for ultrasound guidance or CT guidance. In CBCT guidance, a 3D-volume data set is acquired by rotating a C-arm flat-panel detector angiosystem around the patient. In the data set, a needle trajectory is determined and, after co-registration, a fusion image is created from fluoroscopy and a slice from the data set, enabling the needle to be positioned in real time.ResultsOf the 41 lesions, 22 were malignant, 17 were benign, and 2 were nondiagnostic. The two nondiagnostic lesions proved to be renal cell carcinoma. There was no growth during follow-up imaging of the benign lesions (mean 29 months). This resulted in a sensitivity, specificity, PPV, NPV, and accuracy of 91.7, 100, 100, 89.5, and 95.1%, respectively. Mean dose-area product value was 44.0 Gy·cm2 (range 16.5–126.5). There was one minor bleeding complication.ConclusionWith CBCT guidance, safe and accurate biopsy of a suspected SRM is feasible, especially in hard-to-reach locations of the kidney.Key Points• Cone-beam computed tomography has potential advantages over conventional CT for interventional procedures.• CBCT guidance incorporates 3D CBCT data, fluoroscopy, and guidance software.• In hard-to-reach renal masses, CBCT guidance offers an alternative biopsy method.• CBCT guidance offers good outcome and safety and has potential clinical significance.

“…The simplest way to perform interventions on a cylindrical MRI scanner is the single-step procedure as used in CT-guided interventions. To determine the location of a lesion and to monitor needle position, the patient must be moved into the isocenter of the MRI scanner and then moved back out of the scanner for incremental advancement of the needle using the freehand technique [2,6]. The interventions specified above require needles for aspiration, injection and biopsy that are visible on MRI, laser applicators, RF electrodes, and microwave antennas for ablation that are available from multiple manufacturers.…”

Background MRI is attractive for guiding and monitoring interventional procedures due to its high intrinsic soft tissue contrast and the possibility to measure flow and cardiac function. Methods Technical solutions have been developed for all procedural steps including imaging guidance, MR-safe catheters and instruments and patient monitoring. This has led to widening of the clinical applications. Interventional MRI is becoming increasingly important for the treatment of patients suffering from malignant diseases. The detectability of masses and consequently their accessibility for biopsy is higher, compared to other modalities, due to the high intrinsic soft tissue contrast of MRI. Temperature-dependent sequences allow for minimally invasive and tissue-sparing ablation (A-0 ablation). Conclusion Interventional MRI has become established in the clinical routine for a variety of indications, including biopsies and tumor ablation. Since the economic requirement of covering costs by reimbursement is met and interventional MRI decreases the mortality and morbidity of interventional procedures, broader application of interventional MRI can be expected in the clinical routine in the future.
