HRCT CHEST /HRCT THORAX
- HRCT CHEST/ THORAX Means – High Resolution computed tomography of Chest/Thorax/
- HRCT chest/thorax is basically lungs image scanning by C T SCAN MACHINE.
- HRCT CHEST -The cut of CT Scan is 1/2 mm slice thickness and interslice distance 5 /10 mm window width ( 1000 to 1600 ) and window level (-400 to -700 ) which shows lungs any patchy opacity, pneumonia, smooth septal thickening, or abnormality clearly, So in COVID 19 PANDEMIC Period, the Doctors advice the HRCT CHEST to detect the COVID 19 involvement in lungs.
CO-RADS CLASSIFICATION FOR COVID 19 DIAGNOSIS ACCORDING TO DOCTORS (RADIOLOGIST )
- CORADS-1 Very low suspicion
- CORADS-2 Low suspicion
- CORADS-3 Indeterminate (unclear whether COVID 19 present)
- CORADS-4 High suspicion
- CORADS-5 Very high suspicion
- CORADS-6 Proven by RT-PCR TEST (RTPCR – REVERSE TRANSCRIPTASE POLYMERASE CHAIN REACTION )
RAT –( RAPID ANTIGEN TEST
COVISELF TEST KIT which has been approved by ICMR (Indian Council OF Medical Research)within 15 minutes COVID 19 TEST done, manufactured by My Lab PVT. PUNE (MAHARASHTRA)
NOTE – In the Lungs, there are five lobes, right side 3 lobes, left side 2 lobes. each lobe gives 5 CT scores total of 25 that shows the CT SEVERITY SCORE (ratio) – 25/25(100%), 12-13/25 (50%), 5-10/25(25%) according to infection of lungs.
- LOW 1-5/25
- MILD 5-10/25
- MODERATE 10-15
- SEVERE 15-20/25
- HIGHLY SEVERE 20-25
WHAT IS THE HRCT CHEST TEST?
This test is done by a C T scan machine , The cut of CT Scan is 1/2 mm slice thickness and interslice distance 5 /10 mm window width ( 1000 to 1600 ) and window level (-400 to -700 ) which shows lungs any patchy opacity, pneumonia, smooth septal thickening, or abnormality clearly, So in COVID 19 PANDEMIC Period, the Doctors advice the HRCT CHEST to detect the COVID 19 involvement in lungs.
