Gamma Camera with IQ SPECT-CT

• Advanced Cardiac Imaging: Faster Scans, Reduced Radiation Exposure, and Superior Diagnostics The integration of IQ SPECT technology revolutionizes cardiac imaging at Sir H.N. Reliance Foundation Hospital. This innovative solution collects four times as many counts from the heart during a myocardial perfusion SPECT (MPI) study while maintaining the same resolution as a low-energy, high-resolution (LEHR) collimator.
  • This increased count statistics allows us to significantly reduce acquisition time, completing a comprehensive cardiac workup in less than 5 minutes.
  • Alternatively, we can reduce the injected dose by up to 75 percent without compromising image quality. This flexibility allows us to optimize protocols to suit individual patient needs and minimize radiation exposure.
  • IQ SPECT maximizes detected counts from the heart without truncation, addressing a limitation of conventional parallel hole collimators when imaging small organs like the heart. SMARTZOOM™ collimators utilize magnifying properties near the center of the field of view (FoV) and behave like parallel hole collimators at the edge, allowing the detectors to "zoom in" on the heart for four times more sensitivity.
  • The system employs a cardio-centric acquisition, positioning the heart in the center of the collimator FoV and aligning the detectors at an optimal 28 cm radius to maximize sensitivity.
  • Advanced IQ SPECT reconstruction accurately incorporates the measured geometry of the SMARTZOOM collimators and the cardio-centric orbit, leading to more accurate image reconstruction. This helps to minimize artifacts that can affect image quality in conventional reconstructions that don't fully account for detector motion, gantry deflections, collimator hole size, and patient-detector distance.
  • The enhanced image quality achieved with IQ SPECT, even with faster scans and lower doses, provides superior cardiac imaging with attenuation correction. As demonstrated in clinical studies, 4-minute MPI with IQ SPECT provides image quality comparable to conventional 15-20 minute scans using LEHR collimators, with significant potential for dose savings.
• High-Resolution Detectors for Exceptional Image Quality

  While the sources explicitly highlight the ability of IQ SPECT to maintain resolution comparable to LEHR collimators, our new Siemens Gamma Camera is also equipped with high-resolution detectors (HD detectors). This ensures exceptional image quality across a wide range of applications, benefiting both adult and pediatric patients. This capability, combined with the advanced reconstruction methods of IQ SPECT, allows for detailed and accurate visualization crucial for precise diagnoses.

• 32-Slice CT for Best Fusion Imaging on SPECT-CT

  Our new system features a state-of-the-art 32-slice CT scanner, providing unparalleled fusion imaging quality on SPECT-CT. This powerful combination allows for the anatomical detail from the CT scan to be co-registered with the functional information from the SPECT scan. This precise fusion imaging is essential for accurate diagnosis, treatment planning, and monitoring of various conditions. The diagnostic spiral CT capabilities further enhance the clinical utility of this system.

• Support for Theranostics with High-Energy Detectors

  The Gamma Camera at SIR H. N. RELIANCE FOUNDATION HOSPITAL is equipped with high-energy detectors, making it ideally suited for post-therapy scans of patients undergoing Targeted Radionuclide Therapy. This capability is crucial for effective theranostics, allowing us to visualize and quantify the distribution of therapeutic radiopharmaceuticals. The Symbia Pro.specta Theranostics Edition is specifically designed to meet theranostic needs, and our new system aligns with this advanced platform.

• Enhanced Patient Comfort with a Redesigned Scanner Room and Faster Scans

  We understand that undergoing medical imaging procedures can be a source of anxiety for patients. To address this, SIR H. N. RELIANCE FOUNDATION HOSPITAL has redesigned the scanner room to provide a more comfortable and calming environment. Furthermore, the significantly reduced scan times offered by the IQ SPECT technology for cardiac imaging contribute directly to enhanced patient comfort. Patients can now complete cardiac scans in under 5 minutes, minimizing the need to remain still for extended periods, which can be particularly beneficial for patients with conditions like heart failure or lung disease or those who experience claustrophobia. The shorter scan times also reduce the likelihood of motion artifacts, potentially improving image quality.

  The introduction of this state-of-the-art Siemens Gamma Camera with IQ SPECT-CT technology underscores SIR H. N. RELIANCE FOUNDATION HOSPITAL's commitment to providing our patients with the highest quality care, utilizing the most advanced medical imaging available. This investment will allow us to offer faster, safer, and more accurate diagnostic and theranostic procedures, ultimately leading to improved patient outcomes and satisfaction.

We are excited about the possibilities this new technology brings and look forward to continuing to serve our community with excellence in nuclear medicine imaging.
