Pet mri ppt

Someone is here who will give information about Clinical Applications of PET/MR in Oncology? If you have PPT/ PDF file based on Clinical Applications of PET/MR in Oncology, so provide PPT/PDF file?

As you are looking to know about Clinical Applications of PET/MR in Oncology for your reference:

Clinical Applications of PET/MR in Oncology: Chances and Challenges

Hybrid PET and MRI: technical and diagnostic challenges
PET and MRI both very complex technologies, no „dominating“ part
PET/MR will not replace PET/CT in the midterm
Challenges of simultaneous whole-body PET/MR:
Integration of MRI and PET, new PET Technology (APD, SiPM)
Attenuation Correction of PET by MRI data
Detection/Evaluation of small lung lesions
Complexity of whole-body MR protocols especially in oncology
Patient Comfort
Cost- and time-efficient use of both MRI and PET

Attenuation correction methods for PET/MR
A. Atlas based methods bony structures can be included
non-rigid registration errorprone in the body trunk
individual patient anomalies cannot be not accounted for
resected organs
implants
tumor

Potential new artifacts by MR-AC: truncation
Transaxial FOV of the MR is smaller than the PET-FOV
Parts of the arms, shoulders, hips and breast might be missing in the segmented AC-map

MR coils are not visible on segmented MR-attenuation maps
Static coils (head/neck, spine) and patient bed can be integrated into the AC-map via templates

Surface coils have to be optimized for PET (design, low-attenuatingmaterials), but may introduce errors
