Parsa Hospital Imaging Clinic

Located on the first floor of Building B, the Specialized Imaging Clinic at Parsa Hospital is equipped with the latest international-standard technology. Open 24/7, it provides advanced diagnostic services with precision and efficiency.

CT Scan

At the Parsaa Hospital’s Advanced Medical Imaging Center, CT scans are performed using a Siemens 16-slice CT scan device from Germany, capable of accommodating weights up to 140 kg. General CT scans, contrast-enhanced CT scans, and CT angiography with reconstruction are available.

CT scans use X-rays, where a narrow beam of X-rays (similar to a laser beam) is directed at the patient’s body. These rays pass through all tissues in their path, and the portion that exits the body on the opposite side is detected by sensitive detectors.

These detectors convert the X-rays into electrical signals. This process is repeated from various angles, with the narrow X-ray beam projected at different angles into the body, and the output is measured on the opposite side.

Thus, extensive information is gathered as varying electrical intensities that correspond to the X-rays received by the detector. This data is transmitted to the central CT scan computer. The powerful computer processes the information and produces multiple images showing cross-sections of the body, displayed on the device monitor. If needed, these images can be printed on film.

CT scan images provide much more accuracy than standard X-rays, showing the shape of bones and even many other tissues within the body. This technique also allows viewing inside the bones. Most modern CT scans are spiral or helical, meaning the X-ray source moves around the patient’s body in a spiral, capturing images from different angles. Today’s CT scan images are significantly more detailed, and the devices work at much faster speeds, often completing a scan within a few minutes.

The CT scan machine, also called a computed tomography device, is a medical imaging tool that provides detailed internal views of the body. This device, produced by various manufacturers, includes Siemens CT scans as one of the highest-quality options. Siemens has focused on using the best materials for these devices to ensure ease of use. The reliability and performance of Siemens equipment are well-established, contributing to its prominent reputation.

Features of the Siemens CT Scanner:

1. High Image Quality: Advanced imaging for precise diagnosis.
2. Advanced Software: Enables detailed reconstructions and dose management.
3. Rapid Scanning: Minimal time required, typically completed in a few minutes.

With spiral CT scanning technology, the scanner rotates around the patient in a spiral pattern, capturing high-precision images quickly. Parsa Hospital’s imaging department prioritizes comfort and accuracy, ensuring a seamless experience for all patients.

Digital Mammography

Mammography is a simple X-ray image of the breast and an essential tool for early detection of non-palpable breast cancers. All women aged 40 and above should undergo mammography annually. Women with a first-degree relative (mother, sister, aunt) diagnosed with cancer should begin annual mammography at age 35.

The best time for mammography is after menstruation, as breasts are more sensitive during menstruation. To achieve a high-quality image, pressure is applied to the breast, which may be painful. Before the procedure, take a shower and avoid using talcum powder, deodorants, roll-ons, or sprays, as these substances can lead to misinterpretation of the mammogram.

Mammography can detect breast cancer 10 years before it becomes palpable. It is used to screen women over 40 for breast cancer, assess patients with suspicious breast masses, follow up on treated breast cancer cases with partial mastectomy and radiotherapy, and monitor the opposite breast in individuals who had one breast removed due to cancer. The primary goal of mammography is early detection of breast cancer.

General and Specialized Ultrasound (Doppler, NT, Anomaly, etc.)

Doppler ultrasound is used to visualize blood flow and the movement of internal organs, such as heart valves. “Ultrasound” refers to “beyond” or “above sound” in Persian, representing sound waves with frequencies higher than the human ear can detect but can be traced using specific equipment.

Ultrasound waves pass freely through fluid, soft tissues, and air, but they reflect off denser, more rigid tissues (a phenomenon called echo).

For instance, ultrasound waves easily pass through blood in the heart but reflect significantly when encountering heart valves. Similarly, ultrasound waves pass through bile in the gallbladder but reflect when encountering gallstones.

During the procedure, you lie down while the doctor places a probe (a device the size of a computer mouse) on the area to be examined. The probe emits ultrasound waves and receives their echoes.

A small amount of lubricating gel is applied to the skin to allow the probe to move smoothly and provide better imaging. The probe is connected to the ultrasound machine via a cable, and the ultrasound machine is linked to a display screen.

Preparation for Different Ultrasound Types

1. Abdominal and Pelvic Ultrasound: Patients must fast for 6 hours, and the bladder must be full.
2. Vaginal Ultrasound: The bladder must be empty, and patients experiencing bleeding must bring a disposable underpad.
3. Uterus and Ovaries from the Abdomen: The bladder must be full.

Digital Radiography

Radiography using X-rays (X-ray) is a quick and painless test that captures images of internal structures, particularly bones. X-ray waves pass through the body but are absorbed at varying degrees depending on the density of the materials they pass through.

Dense materials, such as bone and metal, appear white on the X-ray film. Air within the lungs appears black, while fat and muscle show up as varying shades of gray.

In some types of radiographic tests, a contrast medium like iodine or barium is introduced into the body to enhance the visibility of structures in the images. Radiography is a medical imaging technique that provides insight into the body’s internal state, allowing the detection of certain diseases. By directing X-rays (Röntgen rays) at specific body parts, the required images can be obtained.

Digital Panoramic Radiography (Panoramic X-ray)

Almost everyone who has visited a dentist has experienced having their teeth X-rayed. In dentistry, as in other medical fields, radiography is used to aid in diagnosing dental diseases or injuries. These images help determine the presence and extent of cavities or tooth decay.

In an OPG (Orthopantomogram), the upper and lower jaw teeth are visible. The machine typically rotates around your head to capture a comprehensive image of all your teeth. To take this image, any metal objects in the head and neck area, such as earrings or necklaces, must be removed.

Dentists request this type of imaging for various reasons. One application is to evaluate jaw fractures caused by trauma, such as accidents or falls. This imaging can also be used to detect tumors and cysts in the jaws. Additionally, it is necessary before orthodontic treatment or wisdom tooth surgery.
