DWI can't be used as an independent method of diagnosis,
but it complements conventional MRI in lymphomas patients.
At the same time,
we note that to refine the nature of the lesion sighting study,
with optimal for the intended type of lesion diagnostic methods,
should be hold.
MRI of the whole body can also be used as a screening method in oncology even in patients without cancer history.
Compared with PET MRI advantages are a clear reflection of the anatomical structures,
exact location of the lesions and detection of lesions less than the resolution of the PET scanner.
Compared withCE CTwhole-body MRI is more sensitive in patients with focal lesions localized in the unaltered surrounding soft tissues and early inflammatory and post treatment infarction changes of bone marrow.
Considering the signal characteristics we are able indirectly judge the residual activity of lymphoid tissue in patients in remission.
CT saves it predominance in sensitivity,
but not specificity,
in small foci in lungs.
Evaluation of true and false positive results were based on the data of follow-up,
as the histological verification of all lesions in disseminated process is not possible.
The sensitivity of MRI was up to 96%,
specificity of MRI reaches 94%
and overall accuracy is up to 94%
Whole-body MRI is a highly sensitive method for detecting focal lesions,
including oncology nature ones,
with no additional radiation exposure.
This is important to support patients during treatment: it is possible to conduct more frequent and complete control of therapy efficiency in patients with various forms of lymphoproliferative disease,
to improve and to change tactics and strategies of treatment.
Due to the natural blood contrast whole-body MRI allows to evaluate with sufficient accuracy the relationships between lymphoma tumor and vessels.
In some cases this makes it possible to escape contrast enhancement.
