Is there a way to stop pulling in text from a query after a CR is detected?

EX Stuff.Cell:
This is a test.
one
two
three

I would like to just extract "This is a test."

The query below removes anything after CR or LF. If you want to look for only CR, remove the LF and it should work the same way.
DECLARE @x VARCHAR(32) = 'abcd'+CHAR(10)+CHAR(13)+'efgh';
SELECT 
	CASE 
		WHEN @x LIKE '%['+CHAR(10)+CHAR(13)+']%' THEN
			STUFF (@x,PATINDEX('%['+CHAR(10)+CHAR(13)+']%',@x),LEN(@x),'')
		ELSE @x
	END;

Thanks Sunitabeck.

I understand the concept but am a little tripped up with implementing it.

I have a table (td.test) with a list of test names (ts_description) and am trying to remove the text after the first CR in ts_description. I tried to modify your example but am getting a syntax error. Here's the SQL, any help would be greatly appreciated!

SELECT
CASE
WHEN ts_description LIKE '%['+CHAR(10)+']%' THEN
td.test ( ts_description,PATINDEX('%['+CHAR(10)+']%', ts_description),LEN( ts_description),'')
ELSE ts_description
END;
FROM td.TEST

You have a semi-colon before the "FROM" keyword. Semi-colon is end-of-statement indicator. Also, I think the td.test is not required - you need the STUFF keyword
SELECT CASE 
            WHEN ts_description LIKE '%[' + CHAR(10) + ']%' THEN STUFF (
                     ts_description,
                     PATINDEX('%[' + CHAR(10) + ']%', ts_description),
                     LEN(ts_description),
                     ''
                 )
            ELSE ts_description
       END
FROM td.TEST
