Development of clinical simultaneous SPECT/MRI

Area of Science:

• Medical Imaging
• Radiotherapy
• Nuclear Medicine

Background:

• Combined positron emission tomography (PET) and MRI systems are increasingly used clinically.
• No clinical system currently exists for simultaneous single-photon emission computed tomography (SPECT) and MRI.
• Preclinical systems have been developed, but face challenges for clinical translation, including component compatibility and system design.

Purpose of the Study:

• To describe the development of a clinical prototype for simultaneous SPECT/MRI.
• To address the challenges in creating MRI-compatible SPECT components for a compact, stationary system.
• To highlight the clinical potential of integrated SPECT/MRI, particularly for brain tumor management.

Main Methods:

• Focus on the Integrated SPECT/MRI for Enhanced stratification in Radio-chemo Therapy (INSERT) project.
• Addressing technical challenges of SPECT/MRI compatibility.
• Developing a compact and stationary clinical prototype.

Main Results:

• The INSERT project is in an advanced stage of developing a clinical prototype.
• Key issues regarding SPECT/MRI compatibility have been outlined.
• The clinical feasibility and appeal of the integrated system are discussed.

Conclusions:

• Simultaneous SPECT/MRI offers significant potential for clinical applications.
• The development of integrated systems like INSERT is crucial for advancing cancer therapy.
• This technology could enhance patient stratification and treatment monitoring, especially for brain tumors.
