Quick Relief For A Host Of Ailments


Remote instruments introduced through a small puncture in the groin or upper arm are replacing treatments that once required elaborate surgery. Radiology is arguably the fastest expanding medical speciality today, Technology allows doctors to look in real-time at the insides of a patient through super-efficient scans.

They can then repair diseased vessels or organs without having to cut open a patient, using instead remote instruments at the end of a long slim plastic tube introduced through a small puncture in the groin or upper arm just above the elbow.

Procedures That Interventional Radiologists Do Include

Treating Cancer

Radiologists can deliver chemotherapy drugs accurately to the cancer tumour. This can be used to kill off much of the tumour. They block the tumour's blood vessel to prevent the cancer drug from being flushed away. Interventional radiology is also used to fight cancer by using radio frequency waves to destroy small tumours with heat. The end of a needle cooks small tumours in the lung, liver, kidney or bone. The body will gradually remove the dead tissue.

Repairing A Weakened Blood Vessel

A tiny metal frame can be used to strengthen the walls of blood vessels, to heal a tiny tear or prevent the vessel from bursting. A stent - a small metal tube-can be grafted to allow blood to bypass the balloon area. Recovery is fast with fewer complications.

Deep Vein Thrombosis

People with deep vein thrombosis can die when the blood clots float free and end up in the lung. Radiologists can get to the vein and break the clots up into fragments. They can also put a filter into the vein to prevent such clots from moving up the body.

Vertebroplasty

Older people, and some young ones too, suffer from small fractures in the spine. In the elderly, this is often caused by weakening of the bone or osteoporosis. The collapsed vertebra pressing against the spinal cord can cause excruciating pain. Radiologists can insert medical cement into the vertebra to shore up the bone and ease the pressure, giving almost immediate relief.

What Is DNA?

eoxyribonucleic acid, or DNA, is the chemical that makes up the chromosomes in the nucleus of a cell and passes on the characteristics of one generation to the next. It is the substance of heredity. DNA carries all of the genetic information necessary for all cellular functions, including the building of proteins. DNA is composed of sugar (deoxyribose), phosphate, and the four bases adenine, cytosine, guanine, and thymine.
