Major Differences Between CT Scan and HRCT


December , 14 2021


You may have heard about CT scans and HRCT. Many people misunderstand them similarly, but they both are different from one another. We will explain the key difference between these two testing and scanning methodologies briefly.

Both the conventional CT chest scan and HRCT scanning process perform taking snapshots of internal chest organs, but HRCT is deep and analyzes images precisely with 1.25 mm pieces with 20mm expansion and conveys reports to Picture Archiving And Communication System(PACS). Both scanning methods transmit unrefined information restoration as 0.75mm x 0.7mm to the data server. The radiologist will generally assess unrefined picture in both scanning reports, but the resolution of these images tell the difference. The vulnerable and exhaling series of HRCT is also at 1.25mm pieces at 20mm expansion.

An HRCT is a type of CT scan that takes a picture of your chest and lungs to see if any masses or nodules are present. This type of scan will also miss nodules, so it is important to view the raw data and talk to your radiologist about your options if you're not seeing what you need. The higher resolution and HRCT have than normal. An HRCT is typically used in conjunction with a referral from a radiologist or other health care specialist. Unless the radiologist views the image and confirms it was positive, we typically discard this test result because it is incomplete.

Contrary to popular belief, HRCT doesn't need to have a higher resolution than standard CT. They both have the same raw data, so it is wrong to think that. Get HRCT near me at Hamdard Imaging Center. 

The difference lies here: HRCT sequences are more comprehensive than conventional ones. They do two extra, differentiating sequences (expiratory/prone), and they also provide a thinner, text-only version for on-screen viewing on PACS. This way, referring physicians can view it quickly and easily. This solution extracts small quantitative features in the lungs in order to diagnose specific imaging diagnoses, including the presence of cancer.

Rapid technological advancements have created a near-isotropic CT scanner that can acquire an HRCT in one breath-hold. Two approaches need to be used when acquiring these HRCT images. Several data phases are acquired at different time intervals, preserving the typical single breath-hold data acquisition technique, or one large phasing volume is instead collected with two or 3 outputs added.

To get the most accurate diagnosis, you have to have a well-brewed coffee for a long time or use a new one every day. Reconstruction of 4-D images from MDCT scan results is possible by using at least 2 HRCT scans. These scans must be spaced, contiguously, and overlapping to provide a detailed view of interferes with millimeter accuracy.
