The development of whole-body imaging at single-cell resolution enables system-level approaches to studying cellular circuits in organisms. Previous clearing methods focused on homogenizing mismatched refractive indices of individual tissues, enabling reductions in opacity but falling short of achieving transparency. Here, we show that an aminoalcohol decolorizes blood by efficiently eluting th...
objective(s): the objectives of this work was to assess the benefits of the application of physiologically based pharmacokinetic (pbpk) models in patients with different neuroendocrine tumours (net) who were treatedwith lu-177 dotatate. the model utilises clinical data on biodistribution of radiolabeled peptides (rlps) obtained by whole body scintigraphy (wbs) of the patients.methods: the blood...
objective(s): we investigated a frequency of lower extremity uptake on the radioactive iodine (rai) whole body scan (wbs) after rai treatment in patients with differentiated thyroid cancer, in order to retrospectively examine whether or not the frequency was pathological. methods: this retrospective study included 170 patients with thyroid cancer, undergoing rai treatment. overall, 99r (58%) an...
twenty-one patients with medullary thyroid carcinoma were studied prospectively with tc-99m (v) dmsa after surgery. pentavalent dmsa scintigram demonstrated abnormal uptake in 13 and equivocal uptake in 6 patients. finally, seven patients with surgical or other imaging documentation were selected for this paper. most of these patients were asymptomatic. six patients had hypercalcitonemia and se...
Efficient tissue-specific delivery is a crucial factor in the successful development of therapeutic oligonucleotides. Screening for novel delivery methods with unique tissue-homing properties requires a rapid, sensitive, flexible and unbiased technique able to visualize the in vivo biodistribution of these oligonucleotides. Here, we present whole body scanning PCR, a platform that relies on the...
We have recently developed a new model of tumor-host interaction consisting of red fluorescent protein (RFP)-expressing tumors transplanted to green fluorescent protein (GFP) transgenic mice expressing GFP in all tissues. We have previously shown that this model allows the whole-body imaging of tumor growth and metastasis and the visualization of host cells and structures including blood vessel...
fibrous dysplasia of the bone (fdb) is a common, genetic, developmental disorder with a benign course. fdb can be seen anywhere throughout the skeleton. it is usually asymptomatic and found incidentally on imaging studies that are performed for other purposes. although whole body 18 f-flourodeoxyglucose pet/ct (fdg pet/ct) is widely used in tumor imaging, infections and benign pathologies like ...
Most dynamic imaging protocols require long scan times that are beyond the range of what can be supported in a routine clinical environment and suffer from various difficulties related to step and shoot imaging techniques. In this short communication, we describe continuous bed motion (CBM) imaging techniques to create clinically relevant 15 min whole-body dynamic PET imaging protocols. We also...
conclusions: this study provides detailed information and case samples of radiodine contamination artifacts and non-physiological, non-metastatic extra-thyroidal i-131 accumulation in whole-body i-131 imaging. introduction: radioactive iodine has been used for more than 50 years for the treatment of thyroid diseases. differentiated thyroid cancers have the ability to trap iodine. therefore, rad...
Radiol Bras. 2015 Mai/Jun;48(3):IX–X Among others, one particular advantage of whole-body magnetic resonance imaging (wbMRI) is the absence of ionizing radiation, a factor that is especially relevant in pediatric imaging, due to the increased sensitivity of children to ionizing radiation. Another important advantage is the high accuracy of the method in the investigation of bone marrow and soli...
