Abstract:
A 65-year-old woman presented with right upper extremity paralysis and left cerebrovascular accident. A routine complete blood count (CBC) demonstrated Howell-Jolly bodies on peripheral smear, and a liver-spleen scan showed absent splenic sulfur colloid uptake suggesting functional asplenia. A subsequent heat damaged red blood cell study demonstrated a normal sized spleen with preserved sequestering function, thereby excluding anatomic asplenia, vascular alterations, or congenital anomalies in the differential diagnosis of functional asplenia. This case illustrates the use of Tc-99m heat damaged red blood cells as a unique and useful diagnostic aid in identifying the presence and size of a spleen in patients with functional asplenia. It also demonstrates an apparent qualitative separation of splenic functions in processing sulfur colloid and heat damaged red blood cells.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
