Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Imaging Studies for Cardiovascular System V: CT

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Radiological Investigation I: X-ray and CT

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Imaging Studies I: CT and MRI

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
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...

mTOR Signaling and Cancer Progression

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Summary

Computerized tomography (CT) and magnetic resonance (MR) both detect brainstem atrophy in progressive supranuclear palsy (PSP). MR offers superior visualization and measurement of midbrain structures, aiding PSP diagnosis.

Neuroimaging
Neurology
Radiology

Background:

Progressive supranuclear palsy (PSP) is a neurodegenerative disease.
Brainstem atrophy is a key pathological feature in PSP.
Accurate detection of atrophy is crucial for diagnosis.

Purpose of the Study:

To compare the efficacy of CT and MRI in detecting brainstem atrophy in PSP.
To evaluate MRI's capability for quantitative measurements of specific brainstem regions.

Main Methods:

Nine PSP patients underwent CT and MRI brain scans.
Three additional PSP patients had quantitative MRI measurements of the colliculi, pons, and midbrain tegmentum.

Main Results:

CT and MRI demonstrated comparable effectiveness in identifying midbrain atrophy.
MRI's sagittal view revealed thinning of the collicular (quadrigeminal) plate, a significant PSP indicator.
Quantitative MRI confirmed pronounced atrophy in the superior colliculus, a common PSP pathology site.

Conclusions:

Both CT and MRI are effective for visualizing midbrain atrophy in PSP.
MRI provides enhanced visualization of the collicular plate and quantitative atrophy measurements, aiding PSP diagnosis and research.
