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...

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...

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 VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Summary

Dacryoscintigraphy is a valuable imaging test for evaluating epiphora, or watery eyes. This pictorial essay details its findings to aid clinicians in diagnosis.

Area of Science:

Nuclear medicine imaging
Ophthalmology
Diagnostic imaging

Background:

Epiphora (watery eyes) evaluation requires effective diagnostic tools.
Dacryoscintigraphy is a noninvasive imaging technique for assessing the lacrimal drainage system.
Despite its utility, dacryoscintigraphy is underutilized in routine nuclear medicine practice.

Purpose of the Study:

To present a comprehensive pictorial essay of dacryoscintigraphy findings.
To standardize the interpretation of dacryoscintigraphy scans for epiphora evaluation.
To increase the utilization of dacryoscintigraphy in clinical practice.

Main Methods:

Review of dacryoscintigraphy scans performed for epiphora.
Development of a standardized imaging protocol.

Keywords:

Dacryoscintigraphy epiphora nasolacrimal duct
