Prognostic utility of 90Y radioembolization dosimetry based on fusion 99mTc-macroaggregated albumin-99mTc-sulfur colloid SPECT.
UNLABELLED Planning hepatic (90)Y radioembolization activity requires balancing toxicity with efficacy. We developed a dual-tracer SPECT fusion imaging protocol that merges data on radioactivity distribution with physiologic liver mapping. METHODS Twenty-five patients with colorectal carcinoma and bilobar liver metastases received whole-liver radioembolization with resin microspheres prescrib...
متن کاملTranspulmonary passage of 99mTc macroaggregated albumin in healthy humans at rest and during maximal exercise.
We have demonstrated that 50-mum-diameter arteriovenous pathways exist in isolated, healthy human and baboon lungs, ventilated and perfused under physiological pressures. These findings have been confirmed and extended by demonstrating the passage of 25-microm microspheres through the lungs of exercising dogs, but not at rest. Determination of blood flow through these large-diameter intrapulmon...
متن کاملTailoring boundary geometry to optimize heat transport in turbulent convection
By tailoring the geometry of the upper boundary in turbulent Rayleigh-Bénard convection we manipulate the boundary layer-interior flow interaction, and examine the heat transport using the lattice Boltzmann method. For fixed amplitude and varying boundary wavelength λ, we find that the exponent β in the Nusselt-Rayleigh scaling relation, Nu − 1 ∝ Ra, is maximized at λ ≡ λmax ≈ (2π) , but decays...
متن کاملTailoring patient information to encourage patient engagement
This paper proposes a new method for tailoring health information based on an individual’s dominant attitudes and information processing style which can be digitally operationalized and delivered direct to the patient. This individualized approach is based on principles previously used as the basis for mass-marketing campaigns, including smoking and other public health issues but not previously...
متن کاملRelationship of 99mtechnetium labelled macroaggregated albumin (99mTc-MAA) uptake by colorectal liver metastases to response following Selective Internal Radiation Therapy (SIRT)
BACKGROUND SIRT is an emerging treatment for liver tumours which relies on the selective uptake by tumour of 90Y microspheres following hepatic arterial injection. Response rates of around 90% are reported. Hepatic arterial injection of MAA gives an indication of the expected distribution of 90Y microspheres within the liver. This study sought to determine if the MAA scan could be predictive of...
