Aim:
The aim of the study was to evaluate efficacy of percutaneous computed tomography (CT)-guided radiofrequency ablation (RFA) of nidus in osteoid osteoma (OO).
Materials And Methods:
RFA was performed on fifty patients with clinically and radiologically diagnosed OO. RFA was done in the department of radio-diagnosis in our institute (a tertiary care providing institute in Ahmedabad, Western India). Ablation was performed by putting at an electrode tip (3-5 mm) into nidus under CT guidance with targeted temperature of 90°C for 3 min.
Results:
All procedures were technically successful. No immediate major or minor complications were observed. Complete clinical success was achieved in 46 patients. Only four patients required second intervention.
Conclusion:
Our experience indicates a 98% success rate. No major complications were noted.

Computed Tomography
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...

The Role of Ion Channels in Neuronal Computation
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....
