Rapid Nuclear Medicine Blood Volume Analysis for Emergency Assessment.

Assessment of fluid status can play a critical role in the diagnosis and management of emergent conditions such as trauma, shock, decompensated heart failure, syncope, and hypertension. Unfortunately, common methods are all qualitative and/or indirect, and often inaccurate. With the recent introduction of a modernized method of nuclear medicine blood volume analysis (NM-BVA), offering results in 90 min or less as well as improved precision and ease of performance, this decade-old technique is for the first time a viable tool in the emergent setting. In this review, we discuss the history of NM-BVA, the modern method, and our institution's experience implementing this method.

Dosing of radioactive iodine in end-stage renal disease patient with thyroid cancer.

We describe detailed administration of thyroidal and extrathyroidal doses of radioiodine to a patient with end-stage renal disease on hemodialysis. A thorough description of area under curve measurements in a patient with compromised renal function has rarely been described in the literature. Few publications have described thyroid cancer management of patients on hemodialysis, and we believe our management will aid in patient treatment in the future. LEARNING POINTS: Scheduling of hemodialysis is important when administering radioactive iodine.Treatment of thyroid cancer with radioiodine in patients with end-stage renal disease requires multidisciplinary approach coordinating dialysis, nuclear medicine and endocrinologists care.Balancing ideal dosage of I131 and the timing of dialysis to insure maximal thyroidal uptake and minimal extra thyroidal I131 concentration is necessary.
