Deadlocks with simple UPDATE statement

Question

I have in a C# program a dictionary and in SQL Server a stored procedure with a simple UPDATE statement. I process the dictionary in parallel. For each entry in my dictionary I call this stored procedure and I am getting deadlocks.
This is the UPDATE statement:
ALTER PROCEDURE [dbo].[UpdateImages]
@ICRTCode nvarchar(max),
@ICRTImage nvarchar(max)
AS
BEGIN
UPDATE Images SET processed = '1', Image = @ICRTImage, ProcessDate = GETDATE() WHERE IDICRT = @ICRTCode
END
Can someone give me a hint as to why this would cause deadlocks? There are no other processes writing to this table. This is a table in a staging database.

Try change the statement a little bit
UPDATE Images SET processed = '1', Image = @ICRTImage, ProcessDate = GETDATE()
FROM
Images
WITH (TABLOCK) WHERE IDICRT = @ICRTCode
