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...

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...

X-ray Imaging

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:

  • Radiology
  • Gastroenterology
  • Emergency Medicine

Background:

  • Computed tomography (CT) is crucial in emergency settings for diagnosing surgical pathology.
  • Multidetector computed tomography (MDCT) is a key imaging modality for acute abdominal pain.
  • The role of oral contrast (OC) in MDCT for acute abdominal pain requires further evaluation.

Purpose of the Study:

  • To compare the diagnostic performance of abdominal MDCT with and without OC in patients presenting with non-traumatic acute abdominal pain.
  • To assess the impact of omitting OC on CT completion time and diagnostic accuracy.

Main Methods:

  • A one-year study involving 50 adult patients with acute abdominal pain.
  • Patients were randomized into two groups: IV contrast only (Group I) and IV plus OC (Group II).
  • Radiological diagnoses were correlated with clinical, surgical, or pathological outcomes.

Main Results:

  • Diagnostic accuracy was high in both groups (92% vs. 96%), with no statistically significant difference (p=0.99).
  • Mean CT completion time was significantly reduced by 49 minutes when OC was omitted.
  • Positive predictive values were comparable (92.0% vs. 96.0%), with minimal false positives in both groups.

Conclusions:

  • MDCT with IV contrast alone is effective for evaluating acute abdominal pain, including appendicitis and pancreatitis.
  • Eliminating routine OC use can decrease emergency department length of stay and CT completion time without compromising diagnostic accuracy.
