Ionizing & Non-Ionising Radiation

 MRI is a technique that produces topographic images by means of magnetic fields and radiofrequency waves.

The ionizing radiations:

  • Alpha
  • Beta
  • Gamma
  • X-Rays

The non-lonizing radiations are:

  • Radio frequency waves
  • UV rays
  • Microwaves

Alpha and beta rays are particulate radiation (particles) whereas gamma and x- rays are electromagnetic rays. All electromagnetic waves have a constant velocity of 3x108 m/s and no mass.

Corneal Epithelium

Image
 Layers of the cornea: Epithelium (Stratified squamous non-keratinized epithelium)  Bowman's membrane - Acellular; does not regenerate Stroma (Thickest layer) - The stroma can scar, but cannot regenerate Dua's layer (Newly discovered, toughest layer) Descemet's membrane- Ends peripherally as Schwalbe's ring; has regenerative potential Endothelium (Most metabolically active layer)- does not regenerate  The hydration level and transparency of the cornea is maintained mainly by the endothelial cells of the cornea. If the cornea becomes overhydrated, it begins to scatter light and gradually begins to lose its transparency Endothelium possesses Na+/K+ ATPase, which keeps the corneal stroma in a relatively dehydrated state. This helps in maintaining the transparency of the cornea. Endothelial cells decrease in number with age. Other factors contributing to the transparency of the cornea are as follows:  Regular arrangement of corneal lamellae ( Maurice theory ) Peculiar...

The Electromagnetic Spectrum

The electromagnetic spectrum, from  low frequency to high frequency  consists of:  Radiowaves  < Microwaves < Infrared < Visible light< Ultraviolet < X-rays <  Gamma rays W. C. Roentgen  is the father of X-ray and the first medical X-ray by Roentgen was of his wife Anna Bertha's left hand. Physicists  Peter Mansfield  and  Paul Lauterbur  developed MRI-related imaging techniques in medicine and they were awarded the Nobel prize in 2003.

Wolff Parkinson White Syndrome (WPW)

Image
Wolff Parkinson White Syndrome (WPW) is characterized by an abnormal accessory pathway in the heart leading to arrhythmias. Pathology: Born with an accessory pathway, the bundle of Kent which connects the atria and ventricle. The electrical impulses from the SA node reach the ventricles earlier via the accessory pathway as there is no AV nodal delay in this pathway. This leads to the preexcitation of the ventricle and initiation of ventricular contraction. This ventricular contraction is prolonged when the impulse via the AV nodal pathway reaches the ventricles. Most common location of the accessory pathway- between the left atrium and free wall of the left ventricle ECG changes:   Shortened PR interval(typically <120 ms) - because of the early initiation of ventricular depolarization. Prolonged QRS duration (total duration >0.12 seconds)- because of the AV nodal impulse reaching the ventricles after the aberrant impulse. Delta waves - slurred upstroke of QRS c...
