Imaging Studies I: CT and MRI01:14

Imaging Studies I: CT and MRI

96
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...

Ultrasonography01:17

Ultrasonography

4.2K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Imaging Studies for Cardiovascular System III: X-Ray

110
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Ultrasound I: Abdominal Ultrasonography

127
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Radiological Investigation I: X-ray and CT

174
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...

X-ray Imaging01:24

X-ray Imaging

5.2K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Area of Science:

  • Obstetrics and Gynecology
  • Radiology
  • Emergency Medicine

Background:

  • Acute abdominopelvic pain in pregnancy and postpartum presents diagnostic challenges due to overlapping symptoms.
  • Pregnancy-induced physiological changes further complicate the differential diagnosis of obstetric, gastrointestinal, and urinary conditions.

Purpose of the Study:

  • To review critical obstetric emergencies during pregnancy and the postpartum period.
  • To categorize these emergencies into preconception-to-pregnancy and postpartum phases.
  • To emphasize clinical and imaging characteristics of key obstetric emergencies.

Main Methods:

  • Pictorial essay format reviewing obstetric emergencies.
  • Categorization of emergencies into two distinct phases.
  • Emphasis on imaging modalities including ultrasound, MRI, and CT.

Main Results:

  • Covers emergencies such as ectopic pregnancy, placenta accreta spectrum, and uterine rupture.
  • Highlights ultrasound as first-line, MRI for complex cases, and CT for critical scenarios.
  • Underscores the importance of timely and accurate imaging for diagnosis and intervention.

Conclusions:

  • Accurate imaging is crucial for differentiating obstetric emergencies.
  • Imaging guides interventions like uterine arterial embolization and surgery.
  • Enhanced diagnostic precision and multidisciplinary management improve maternal and fetal outcomes.
