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...

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 the...

Imaging Studies III: Computed Tomography

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Summary

A rare cause of a child refusing to walk is discitis, an infection of the intervertebral disc. Early diagnosis with spinal magnetic resonance imaging (MRI) is crucial for prompt treatment and recovery.

Background:

Refusal to walk or weight-bear in previously mobile children is a common emergency department presentation.
Lumbosacral discitis is an uncommon but treatable cause of this symptom.
Diagnosis can be delayed due to the absence of typical symptoms like back pain or neurological deficits.

Observation:

A case series of three children presenting with non-weight-bearing gait is described.
None of the children had back pain, spinal symptoms, or abnormal neurological findings.
Full range of motion in both hips was noted in all patients.

Findings:

Conventional radiography and ultrasound were performed, but spinal magnetic resonance imaging (MRI) confirmed the diagnosis of discitis.
There was a mean diagnostic delay of 15.6 days from hospital presentation to MRI.
All patients recovered well with intravenous antibiotics.

Implications:

Highlights the importance of considering discitis in children who refuse to bear weight, even without typical symptoms.
Emphasizes the diagnostic value of spinal MRI for lumbosacral discitis.
Suggests a need for revised guidelines for radiological investigations in this clinical scenario to reduce diagnostic delays.
