99m Tc-Macroaggregated Albumin Liver Lung Shunt Study With Uptake Indicative of Patent Falciform Artery.

Intra-arterial injection of radioactive isotope 90-yttrium 90 Y has been used for elective internal radiation therapy for the treatment of localized hepatocellular carcinoma deemed surgically unresectable. It has also been used to treat intrahepatic cholangiocarcinoma and colorectal cancer that has metastasized to the liver. To prepare for 90 Y treatment, preprocedural mapping via hepatic angiography and 99m Tc-macroaggregated albumin liver lung shunt study followed by postprocedural 90 Y SPECT/CT is essential to ensure a targeted therapy.

Bilateral Axillary Nodal Uptake on 99m Tc-White Blood Cell Study Secondary to COVID-19 mRNA Vaccination.

A 77-year-old man with a history of chronic lower back pain, and prior spinal fusion surgery X2 was referred for 99m Tc-WBC Study for evaluation of worsening back pain and cervical radiculopathy to rule out any signs of infection. The patients white blood cells were tagged with 99m Tc-HMPAO (hexamethylpropylene amine oxime), and planar and SPECT/CT imaging was performed at 4 and 24 hours. 99m Tc-WBC Study showed no abnormal isotope localization in the spine; however, there was an incidental finding of bilateral increased soft tissue uptake in axillary lymph nodes.

The effects of the COVID-19 pandemic on patients with obesity undergoing bariatric care.

Background: Patients with obesity are at increased risk of developing severe COVID-19. The pandemic has caused delays in preoperative preparation, progression, and completion of bariatric surgeries.

Objectives: The aim of this study was to evaluate the impact of COVID-19 restrictions on bariatric surgery patients and assess their concern of COVID-19 as they continue the preoperative process.
