Ultrasonography01:17

Ultrasonography

7.4K
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...

Ultrasound I: Abdominal Ultrasonography

1.5K
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...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Leaky Scanning

5.7K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Cranial Bones: Superior and Posterior View

5.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Scanning Electron Microscopy01:07

Scanning Electron Microscopy

5.4K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Summary

Ultrasonography (US) accurately diagnoses retinal tears (RT), predominantly in the superior quadrants. This finding aids ophthalmologists in training and surgical decisions when the retina is obscured.

Area of Science:

  • Ophthalmology
  • Medical Imaging

Background:

  • Fundus examination is not always possible for diagnosing retinal tears (RT).
  • Ultrasonography (US) is an accurate diagnostic tool when direct visualization is limited.

Purpose of the Study:

  • To determine the predominant location of RT using US.
  • To identify factors influencing RT location and assess vitreous status in affected eyes.

Main Methods:

  • Prospective study of 101 eyes diagnosed with RT via B-scan US.
  • Primary endpoint: RT preferential location.
  • Secondary endpoints: posterior vitreous detachment (PVD) rate, multiple RT, and axial length (AL).

Main Results:

  • Retinal tears (RT) were predominantly located in superior quadrants (71%).
  • All patients had posterior vitreous detachment (PVD); 79% experienced vitreous hemorrhage.
  • Eyes without superior RT had significantly longer axial lengths (AL).

Conclusions:

  • Superior location of RT is common, as diagnosed by US.
  • Shorter axial length (AL) is associated with superior RT.
  • US findings can enhance RT detection sensitivity and aid ophthalmologists, especially trainees and in cases of media opacity.
