Computed Tomography01:10

Computed Tomography

8.1K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...

The Colonization of Land

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Diabetes: Symptoms, Diagnosis, and Complications

2.1K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Area of Science:

  • Radiology
  • Oncology
  • Surgical Gastroenterology

Background:

  • Postoperative complications following colorectal cancer surgery are frequently encountered in emergency departments.
  • Multidetector computed tomography (MDCT) is vital for monitoring patients after surgery, aiding in the detection of both cancer recurrence and complications.
  • Accurate interpretation requires radiologists to understand diverse surgical techniques and typical postsurgical imaging findings.

Purpose of the Study:

  • To review normal multidetector computed tomography findings after colorectal cancer surgery.
  • To outline common early complications in postsurgical colorectal cancer patients presenting to emergency departments.

Main Methods:

  • Review of multidetector computed tomography (MDCT) findings.
  • Analysis of normal postsurgical changes.
  • Identification of common early complications.

Main Results:

  • MDCT is instrumental in identifying normal postsurgical changes and early complications.
  • Distinguishing normal findings from complications is critical for timely patient management.

Conclusions:

  • Radiologists must be knowledgeable about postsurgical changes on MDCT to effectively diagnose complications and recurrence after colorectal cancer surgery.
  • This review provides essential information for interpreting MDCT scans in the context of postsurgical colorectal cancer patients, particularly those presenting to emergency departments.
