Features & Benefits

More clarity for more patients

We re-engineered SPECT/CT bone imaging to use CT as the frame-of-reference during image reconstruction. The higher image resolution achieved from xSPECT Bone™ technology enables you to better localize and characterize disease for a more accurate representation of each patient’s condition.

As patient populations continue to age, the growing presence of metal implants and pacemakers adds complexity to imaging. iMAR, our CT metal-artifact-reduction technique, helps improve both CT and SPECT attenuation correction in these cases.² xSPECT Bone and iMAR can easily be combined for even greater image clarity.

Dose reduction without compromise

For quick and conclusive answers to clinical questions, you need the best image for each patient. However, striking the right balance between image quality and radiation dose can be a challenge, particularly given today’s diverse patient population. Our proprietary CT image reconstruction software and hardware, SAFIRE, lets you accomplish this—quickly and easily.³

The right care at the right time

Adding reliable quantification to your clinical routine can facilitate quicker consensus and generate greater consistency across your institution. Our xSPECT Quant™ and Broad Quantification™ technologies generate highly accurate and reliable measurements to support early diagnoses and optimal therapeutic strategies for a wide array of clinical indications.

xSPECT Bone sharply delineates severe osteoarthritis in the left hip joint

A 71-year-old male with severe left hip pain during motion underwent a 99mTC MDP bone SPECT/CT of the pelvis and lumbar spine. xSPECT Bone™ sharply delineates increased uptake in left acetabulum corresponding to irregular articular surface, peri-articular sclerosis, and narrowing of joint space seen on CT. Sharp definition of joint space and acetabular margins seen on xSPECT Bone helps accurately define the extent of acetabular hypermetabolism and the site of pain.

In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the for the particular clinical task. Data on file.

Reducing metal artifacts with iMAR may lead to more accurate quantification

Iterative metal artifact reduction (iMAR) results in the resolution of the vast majority of artifacts associated with dental implants in this head and neck case, which can result in more accurate assessment of functional activity.

Scanner: Symbia Intevo Bold™ SPECT/CT

The amount of metal artifact reduction and corresponding improvement in image quality depends on a number of factors including: composition and size of the metal object, patient size, anatomical location and clinical practice. It is recommended to perform reconstruction with iMAR enabled in addition to conventional reconstruction without iMAR.

Reducing image distortion with iMAR may improve accuracy of image interpretation

Artifacts from bilateral hip prosthesis can result in severe distortion of adjacent anatomical structures. With iMAR, these artifacts are significantly reduced, resulting in images that more accurately reflect anatomy and thus may lead to more accurate image interpretation.

iMAR helps visualization of anatomical and functional findings in areas impacted by metal artifacts

iMAR reduced metal artifacts from the right hip prosthesis, enabling a more thorough inspection of the pelvis.

xSPECT Quant enables quantification of tracer uptake to support therapy response assessment

A 22-hour post-injection SPECT/CT scan using xSPECT Quant™ showed heterogeneous tracer uptake in the known primary tumor of the pancreas. xSPECT Quant enables quantification of uptake, which allows dosimetric estimation and assessment of therapeutic response. The use of SAFIRE helped to significantly reduce the noise in the CT image.

xSPECT Bone sharply delineates bony remodeling and facet arthropathy secondary to vertebral fixation

xSPECT Bone™ sharply delineates skeletal hyper metabolism in the left facet joints of L3-L5 vertebra adjacent to vertebral stabilization pins reflecting bony remodeling and facet arthropathy, which are secondary to vertebral fixation.
