Recent advances in Gd-chelate based bimodal optical/MRI contrast agents

Abstract: Research on bimodal contrast agents in general and optical/MRI contrast agents in particular has attracted increased attention from the scientific community in recent years. Whereas optical contrast agents reveal pathologies at the cellular or sub-cellular level, MRI contrast agents generally report physiological differences at the level of tissues and organs. The complementary information obtained from these two techniques allows for a more precise diagnosis. Furthermore the emergence of near-infrared luminop… Show more

“…This approach also F bimodal CA, [50] although this is a drop in the ocean of other contrasts with MRI as one of their modalities. [82] Contrast agents are expected not only to serve with their static relation-accelerating features accumulating in the region of interest during an examination of the patient's body. Activation through various stimuli is required, and this quest has also been launched with iron complexes.…”

“…MR and optical imaging are an attractive combination that can be used to determine both molecular and anatomical information. 60 NIR-MR contrast agents not only provide detailed anatomic imaging but also can be used to image molecular targets at low concentrations with high sensitivity. 61 …”

“…Even though MRI has several advantages over its counterparts (PET, SPECT and CT), like its high spatial and temporal resolution, excellent tissue penetration depth, and non-usage of radioisotopes or X-rays, [2][3][4] it is still restricted in the clinical practice to detecting disparities in magnetic properties of tissues and organs mainly because of its low contrast. 5 So far, great efforts have been devoted to increase the low intrinsic contrast of tissues by adding some external agents called contrast agents (CAs). In an another approach, the higher signal-to-noise ratio and thus greater spatial and temporal resolutions can be achieved by using high eld MRI detectors.…”
