Impact Of Cryoablation On Tumor Immunity
<p>Background and Objectives: Percutaneous cryoablation is a minimally invasive procedure for tumor debulking, which has the potential to initiate or amplify tumor immunity through the release of tumor-associated antigens and endogenous danger signals. However, enhanced immunity is rarely observed …

Multi-probe robotic positioner for cryoablation in MRI
… accurate targeting of multiple probes during cryoablation and other percutaneous interventions performed in closed bore magnetic resonance (MR) imaging systems. The device is intended to be mounted onto a Siemens 110 mm MR loop coil that rests on the patient and contains a cable driven …

Renal Cryoablation: Investigation of Periprocedural Visualization to ols and Treatment Response Quantification
<p>Cryoablation for small renal tumors has demonstrated sufficient clinical efficacy over the past decade as a non-surgical nephron-sparing approach for treating renal masses for patients who are not surgical candidates. Minimally invasive percutaneous cryoablations have been performed with image …

Radiofrequency ablation versus cryoablation in the treatment of atrioventricular nodal reentrant tachycardia
… modalities of ablation, radiofrequency (RF) and cryoablation are commonly utilized in clinical practice with high levels of success in treating AVNRT. To date, studies on the two modalities have compared metrics such as acute success rate, procedure time, fluoroscopy time, and recurrence of …

Η κρυοκατάλυση (cryoablation) ως εναλλακτική της συντηρητικής χειρουργικής θεραπείας στον πρώιμο καρκίνο του μαστού
Ο καρκίνος του μαστού αποτελεί την πιο συχνή κακοήθεια στο γυναικείο πληθυσμό. Η ευρεία εφαρμογή εθνικών προγραμμάτων προσυμπτωματικού ελέγχου (screening), η ευαισθητοποίηση των γυναικών καθώς και η βελτίωση των απεικονιστικών μεθόδων έχουν ως αποτέλεσμα τη διάγνωση του καρκίνου του μαστού σε …

Thermal Ablation Alters The Tumor Microenvironment Activating A Robust Immune Response.
… including radiofrequency ablation (RFA) and cryoablation have been shown to influence the immune system in animal models. Rare abscopal events, a distant metastatic response to a local procedure, have been observed in humans following both RFA and cryoablation. These rare observations have …

Biomechanical Assessment and Monitoring of Thermal Ablation Using Harmonic Motion Imaging for Focused Ultrasound (HMIFU)
… procedure with imaging-guidance, such as cryoablation, laser ablation, radio‐frequency (RF) ablation, and High Intensity F-ocused Ultrasound (HIFU). HIFU is a non-invasive procedure aims to coagulate tissue thermally at a localized focal zone created with noninvasively emitting a set of …
