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.

Clinical Use

Metal Artifact Reduction
Quantification
Orthopedics
With iMAR vs. without iMAR

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.

With iMAR vs. 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.

With iMAR vs. without iMAR

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.

22-hour post-injection SPECT/CT scan

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

A 22-hour post-injection SPECT/CT scan using xSPECT QuantTM 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.

Metastatic lesion

Quantification of therapeutic dose in metastatic lesions with 177Lu PSMA

xSPECT QuantTM allows accurate determination of activity in multiple osseous lesions following therapy with 177Lu PSMA. xSPECT Quant also enables dosimetry applications in order to achieve the highest possible dose to sites of disease while minimizing toxicity risks.

Suspicious right adrenal gland lesion

xSPECT Quant used in 123I MIBG study to accurately evaluate uptake in suspected right adrenal pheochromocytoma

xSPECT QuantTM allows for a more accurate evaluation of radiotracer uptake of a suspicious right adrenal gland lesion. Quantification can be helpful in the initial assessment of disease as well as monitoring the therapeutic response.

Bony remodeling and facet arthoropathy

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

xSPECT BoneTM sharply delineates skeletal hypermetabolism in the left facet joints of L3-L5 vertebra adjactent to vertebral stabilization pins reflecting bony remodeling and facet arthropathy, which are secondary to vertebral fixation.

Loosening of fixation plate

xSPECT Bone sharply defines cervical vertebral instability that is secondary to loosening of fixation screw

99mTc MDP Bone SPECT/CT was performed to evaluate loosening of fixation plate. xSPECT BoneTM shows sharp delineation of focal increased uptake in the bodies of C6 and C7 around the margin of the anterior fixation plate, which suggests hypermetabolism related to bone stress that is secondary to instability and loosening of the anterior fixation plate and screw.

xSPECT Bone/CT fusion

xSPECT Bone sharply delineates bilateral pars fracture in lumbar vertebrae

A 15-year-old female involved in sports presented with lower back pain. xSPECT BoneTM shows sharp delineation of focal increased uptake corresponding to bilateral pars fracture in L4 vertebrae, which are delineated on the CT with higher intensity of uptake in the left side.

xSPECT Bone/CT fusion

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 BoneTM sharply delineates increased uptake in left acetabulum corresponding to irregular articular surface, peri-articular sclerosis, and narrowing of joint space seen on CT.

2The 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 reconstructions with iMAR enabled in addition to conventional reconstruction without iMAR.

3In 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 physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
