Stay competitive in a growing and dynamic field

The number of CT-guided interventions performed is expected to grow rapidly. While biopsies will remain the core application, therapeutic procedures are expected to become much more important due to the obvious advantages of minimally invasive therapy: fewer complications, faster recovery times, and shorter hospital stays.

New guidelines 

The growing importance of thermal ablations in cancer treatment is highlighted by a number of new guidelines.5,6

The image shows an increase of 8 percent.

Increase in ablations 

Ablation procedures in cancer therapy are projected to increase by 8 percent per year between 2020 and 2030.7

Overview
The image depicts the laser cross projected onto the patient's body, along with an ablation probe beginning to penetrate the skin. Additionally, the green cross of the laser guidance system aligns with the hub of the needle, aiding the user in determining the correct angle for inserting the needle along the preplanned path.

myNeedle Laser 

myNeedle Laser9 is a powerful, fully integrated option designed to make the intervention workflow more efficient by automatically projecting the needle entry point and insertion angle onto the body of the patient – even in advanced double-angulated procedures with multiple needle paths.

Probe Planning myAblation Guide liver ablation

myAblation Guide

myAblation Guide10 brings unprecedented consistency to your microwave liver ablation workflow. With sophisticated planning tools, easy postprocedural assessment, and a coherent user experience across imaging and ablation systems, we’ve got you covered every step of the way.

CT-guided interventions Adaptive 3D Interventions Suite

myNeedle Guide 3D 

myNeedle Guide 3D11 simplifies the workflow for both routine and complex CT-guided interventions. You can easily plan multiple needle pathways in different cross sections. Both path planning and visually guided insertion of multiple needles are supported within the workflow. 

The AI based needle detection algorithm myNeedle Detection12 supports an efficient workflow by minimizing user interaction when progressing the needle. 

Integrated Image Fusion allows fusing of 3D images from different modalities or contrast-enhanced prior CT studies to accurately plan and guide needle paths around critical anatomy.

Cryoablation of an adrenal metastasis under CT guidance

Cryoablation of an adrenal metastasis

An adrenal metastasis located between the kidney and aorta required complex probe placement through a transpulmonary approach. Using myNeedle Guide 3D and myNeedle Laser, clinicians accurately placed six cryoprobes, with no recurrence observed at the three-month follow-up.
Percutaneous lung biopsy of a small metastatic nodule under CT guidance

Percutaneous lung biopsy of a small metastatic nodule under CT guidance

A 6×8 mm metastatic lung nodule in a difficult paravertebral location made direct biopsy access challenging. Using myNeedle Laser and myNeedle Guide 3D, clinicians captured the lesion on the first attempt and discharged the patient on the same day.
