Computed Tomography for OncologyYou think ahead. We innovate ahead.

Cancer incidence is on the rise: by 2030, there will be almost 20 million new cases per year.1 Thanks to its ability to provide ever more detailed and precise images, Computed Tomography is a key player in the comprehensive management of cancer patients – from initial diagnosis to treatment planning, monitoring, and follow-up.Ìý
You think ahead in advancing cancer care. We innovate ahead with technologies that support you throughout the entire patient pathway. Explore how it can help you provide state-of-the-art care to your oncology patients.

Quantum Spectral Imaging

The photon-counting technology powering the NAEOTOM Alpha class offers spectral information by default. This native integration of Quantum Spectral Imaging means clinicians can access PACS-ready results featuring customizable and fully automated reconstructions without additional effort. Get ready to visualize, characterize, and quantify materials in great detail.

Innovating CT in oncology

The NAEOTOM Alpha class of photon-counting CT systems is designed to revolutionize imaging through precise and improved tissue differentiation. With the improved visualization, photon-counting CT has the potential to impact patient pathways thanks to high resolution supporting early detection and improved diagnostic accuracy.

Pancreatic tumors: clinical evidence

Pancreatic tumors: clinical evidence

Recent studies show that photon-counting CT is a significant asset when it comes to pancreatic tumors. The next-level image quality results in good visibility, facilitating early detection of cysts and tumor characterization.

Advancing tumor detection with CT

Early diagnosis is key for ensuring the best possible treatment and overall outcomes in cancer cases. To achieve this, more and more screening programs for lung cancer and other tumors are being instated around the world. Frequent CT scans mean cumulative patient dose levels are increasingly a key consideration that healthcare providers face. Thankfully, the entire Siemens Healthineers CT portfolio offers low-dose protocols, making them an excellent choice for cancer screening programs.

Low-dose protocols

The dose values of Siemens Healthineers CT systems are the lowest in the healthcare industry.

The dose values contained therein and shown above were submitted by the respective manufacturers to AAPM for publication. SOMATOM Pro.Pulse and NAEOTOM Alpha values are taken from Siemens Healthineers’ internal measurements that have not been published via AAPM yet. The overview reproduces the data from the source and does not claim to be complete. Competing systems with different dose values may be available on the market.

Boosting CT-guided interventions and radiation therapy with CT

With the aid of screening programs, it has become possible to detect more early-stage patients than ever. This is a huge win for patient health: in the case of lung cancer, for instance, there exists an inverse relation between stage and survival in lung cancer.2Ìý

Many of these early-stage cancer patients require advanced treatment options. With a comprehensive portfolio from Siemens Healthineers, your procedures are supported by myNeedle Companion and myAblation Guide. And: our excellent solutions for radiation therapy help ensure consistent imaging results.


CT-guided support in interventions

Minimally invasive ablation procedures in cancer cases are projected to increase by 8% per year between 2020 and 2030.3 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.Ìý

Our portfolio of CT scanners and advanced technologies support both routine and complex CT-guided interventions. They can help you plan needle paths and provide visual guidance for reaching the target area. Studies suggest that advanced technologies such as our integrated laser guidance system have the potential to increase efficiency, reduce radiation dose, and improve accuracy.4 In addition to these benefits, our solutions are designed to streamline your workflows thanks to full in-room control over relevant parameters.

In this talk, Professor Kristina Ringe, MD, from the Medical School of Hannover, Germany, showcases the use of myNeedle Companion for cryoablation of a desmoid tumor in a 32-year-old female patient.

The combination of SOMATOM X.cite and myNeedle Companion are helping David L. Lacey, MD from University of Iowa Hospitals and Clinics in Iowa City, USA, improve CT-guided interventions.

Optimizing treatment plans in radiation therapy

Around 40% of cancer patients will undergo radiation therapy as part of their cancer treatment.4 CT plays a pivotal role, as the CT planning image is the foundation of the whole radiation therapy workflow. Our portfolio for radiation therapy planning is optimally suited to help you achieve consistent imaging results even in moving anatomy.Ìý

Direct i4D technology can reduce breathing artifacts, allowing you to capture detailed images of lesions that can subsequently be contoured with high precision.

Intelligent 4DCT imaging

Irregular breathing can lead to artifacts that interfere with tumor contouring. Our CT portfolio is equipped with Direct i4D: the world’s first 4DCT sequence that intelligently adapts to the patient’s breathing pattern in real time. Download this white paper to see the impact.


To automate contouring, we have developed DirectORGANS. This AI-based tool leverages optimized and standardized reconstruction parameters and processes them through a deep-learning contouring solution. Available directly at the scanner, DirectORGANS makes autocontouring part of your regular reconstruction process.
