Imaging Studies III: Computed Tomography

61
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...

Cranial Bones: Lateral View

2.8K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Olfactory Receptors: Location and Structure

9.7K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Area of Science:

  • Anatomy
  • Radiology
  • Surgical Planning

Background:

  • The olfactory fossa (OF) is a complex anatomical region crucial for olfactory function.
  • Detailed morphometric and morphologic data of the OF are essential for neurosurgical procedures.

Purpose of the Study:

  • To investigate the morphometry and morphology of the olfactory fossa (OF) using computed tomography (CT).
  • To establish normative data for OF dimensions and patterns.

Main Methods:

  • Macroscopic examination of 50 Greek adult dried skulls for OF morphological patterns.
  • Multiplanar CT reconstruction and digital ruler measurements for OF morphometry.

Main Results:

  • Types I and II surface contours were most common (36% and 32%).
  • Mean crista galli dimensions: length 19.46 mm, height 12.69 mm, width 5.18 mm.
  • OF dimensions showed symmetry, with a significant anteroposterior increase in width and a negative correlation between depth and width in anterior/middle thirds. No gender impact was observed.

Conclusions:

  • The study provides valuable morphometric data for the olfactory fossa.
  • Understanding OF anatomy and dimensions aids in successful surgical planning and complication reduction.
