HOW TO INTERPRET HRCT REPORT
WHAT IS CO-RADS ? WHAT IS CT SEVERITY SCORE ?

HRCT REPORT TEMPLATE
LOW DOSE H.R.C.T. CHEST SCREENING (L.D.C.T.S.):
IMPRESSION:
Findings are suggestive of atypical viral pneumonia, possibility of COVID-19 infection. (CO-RADS V).
CT severity score 9 / 25 (Moderate)
    

What is CO-RADS???
•CO–RADS is a categorical assessment scheme used for reporting of chest CT patients, suspected of COVID-19.
•It represents the level of suspicion for pulmonary involvement.
For example, if CO-RADS is level 5 then there is very high surety for Typical COVID-19 findings.


CO-RADS
LEVEL OF SUSPICION FOR COVID-19 INFECTION
CT Findings
CO-RADS 1
No
Normal or non-infections abnormalities
CO-RADS 2
Low
Abnormalities consistent with infections other than COVID-19
CO-RADS 3
Intermediate
Equivocal findings for COVID-19 infections
CO-RADS 4
High
Abnormalities suspicious for COVID-19 infection
CO-RADS 5
Very high
Typical COVID-19 findings
CO-RADS 6
PCR +
HOW TO READ HRCT
CO-RADS 5 means there is very high suspicion of COVID-19 infection in this particular patient with typical COVID-19 findings.

SCORE
THERE ARE TWO LUNGS. Right Lung and Left Lung Right lung is divided in three lobes.
UPPER LOBE, MIDDLE LOBE, LOWER LOBE
Left lung is divided in two lobes.
UPPER LOBE AND LOWER
LOBE
EACH LOBE IS GIVEN SCORE 1 TO 5 BASED ON LUNG INVOLVEMENT.

HRCT SEVERITY (TOTAL SCORE 25)


INFECTION CRITERIA ( SINGLE LOBE):
5 % INFECTED 5-25 % INFECTED 25-50 % INFECTED 50-75 % INFECTED ➢ 75 % INFECTED
: SCORE 1 : SCORE 2 : SCORE 3 : SCORE 4 : SCORE 5
Score calculation is done based on each lobe involvement.
Each lobe has maximum score 5.
And so 5 lobes has maximum score of 25.
For example, score 5 means that lobe is > 75% involved or affected by COVID- 19.

CT SEVERITY SCORE 9 OUT OF 25 means lungs are moderately infected with COVID-19 in this particular patient.
