WHAT IS CO-RADS ?

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???

CORADS 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.

WE ARE TAKING CARE FOR YOU FOR YOUR PATIENTS…

We Have Designated Two CT Scan Machines, 1. For COVID-19 Suspected Patients &
2. For Non-COVID Patients.

A Separate X-Ray Machine Has Been Arranged For Suspected COVID-19 Patients X-Ray Study …

ALL NECESSARY PRECAUSIONS HAVE BEEN TAKEN TO PREVENT CROSS-INFECTION OF COVID-19 TO OTHER PATIENTS & TO STOP VIRUS SPREAD TO SOCIETY…
