Diagnostic Imaging is a pivotal part of health care in diagnosing the reasons for patients health complains. There are different imaging techniques such as x-rays, ultrasound scans, MRI and CT scans. All these tests involve creating images of the internal organs of the body one way or another and these images are used for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology).
X-ray is the oldest imaging technique and it is most commonly used to produce images of bones.
X-rays are usually carried out in NHS or Private hospital X-ray or Radiology departments by radiographers. Other healthcare professionals, such as dentists also use x-rays to image body parts specific to their profession.
How X-rays work
X-rays use ionising radiation to produce the image.
X-rays pass from one side of the body to the other and being absorbed different depending on the density of the body structures they meet. By the time they reach the detector some of the radiation energy has been absorbed by the body and that correlates to white parts on the image. The radiation that did not absorb by the body correlates to the white areas of the image.
When X-rays are used
X-rays can be used to examine most areas of the body. They're mainly used to look at the bones and joints, although they're sometimes used to detect problems affecting soft tissue, such as internal organs.
Problems that may be detected during an X-ray include:
bone fractures and breaks
tooth problems, such as loose teeth and dental abscesses
scoliosis (abnormal curvature of the spine)
non-cancerous and cancerous bone tumours
lung problems, such as pneumonia and lung cancer
dysphagia (swallowing problems)
heart problems, such as heart failure
X-rays can also be used to guide doctors or surgeons during certain procedures. For example, during a coronary angioplasty – a procedure to widen narrowed arteries near the heart – X-rays can be used to help guide a catheter (a long, thin, flexible tube) along one of your arteries.
A computerised tomography (CT) scan sometimes referred as CAT scan, uses X-rays and a computer to create detailed images of the inside of the body.
They're carried out in the hospital by specially trained operators called radiographers and can be done while you're staying in the hospital or during a short visit.
When CT scans are used
CT scans can produce detailed images of many structures inside the body, including the internal organs, blood vessels and bones.
They can be used to:
diagnose conditions – including damage to bones, injuries to internal organs, problems with blood flow, stroke, and cancer
guide further tests or treatments – for example, CT scans can help determine the location, size and shape of a tumour before having radiotherapy, or allow a doctor to take a needle biopsy (where a small tissue sample is removed using a needle) or drain an abscess
monitor conditions – including checking the size of tumours during and after cancer treatment
CT scans wouldn't normally be used to check for problems if you don't have any symptoms (known as screening).
This is because the benefits of screening may not outweigh the risks, particularly if it leads to unnecessary testing and anxiety.
Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body.
An MRI scanner is a large tube that contains powerful magnets. You lie inside the tube during the scan.
An MRI scan can be used to examine almost any part of the body, including the:
brain and spinal cord
bones and joints
heart and blood vessels
internal organs, such as the liver, womb or prostate gland
The results of an MRI scan can be used to help diagnose conditions, plan treatments and assess how effective previous treatment has been.
What happens during an MRI scan?
During an MRI scan, you lie on a bed that's moved into the scanner.
Depending on the part of your body being scanned, you'll be moved into the scanner either head first or feet first.
Daniela Stan is a London based NHS and Private Consultant Sonographer, with more than 20 years’ experience in Healthcare. She holds a degree from the University of Medicine and Pharmacy Carol Davilla, Bucharest, Romania and a Medical Doctor License in Family Medicine.
After graduating from the Medical School Program in 1997, Daniela became fascinated with the field of Diagnostic Imaging and accepted an invitation from one of the leading USA ultrasound institutes to enrol for a Diagnostic Medical Ultrasound Diploma, which she mastered in 2001. Seeking to expand her knowledge and skills, Daniela completed extensive formal ultrasound training and internships in the most renowned USA university hospitals and trauma centers in NY and NJ. Being exposed to diverse pathologies and a multitude of clinical scenarios, Daniela has built a solid core of medical knowledge and experience in her field of interest.
On obtaining the degree in Medical Ultrasound, Daniela was offered a teaching job position at the Institute to teach diagnostic ultrasound to postgraduate students, with concurrent appointments in university hospitals such as Robert Wood-Johnson Trauma Center. She worked closely with vascular surgeons and university medical professors, assisting them with ultrasound in the operating theatre on a broad range of interventional procedures.
From 2003 to 2011, while in USA, Daniela completed the following ARDMS (American Registry of Diagnostic Medical Sonography) ultrasound specialties: Obstetrics (2004), Abdomen and Small Parts (2005), Breast (2008) and Vascular (2010).
Daniela relocated to England in 2011 to join the ultrasound team at Royal Free Hospital NHS Trust, where she performed and reported on the full range of ultrasound scans including Abdomen, Pelvis, Obstetrics, Small Parts, Breast, Vascular and Musculoskeletal in her capacity as Advanced Practitioner Sonographer.
Daniela obtained a Master’s in Medical Ultrasound from Bournemouth University in 2014, earning more than 180 credits in Musculoskeletal Ultrasound and MSK injections alone.
Daniela has been a member of ARDMS (American Registry of Diagnostic Medical Sonography) since 2003 and of APCA (Alliance of Physician Certification & Advancement) since 2015. Since her arrival in the UK in 2011, Daniela has been a member of SOR (Society of Radiographers) and BMUS (British Medical Ultrasound Society).
Sonoworld Diagnostic Services, the Private Ultrasound Practice at Hale Clinic, is Daniela’s latest achievement.
At Sonoworld Diagnostics Daniela offers complex ultrasound examinations including Abdomen, Pelvis, Obstetric, 3D/ 4D, Head and Neck, Breast, Soft tissue lumps and bumps, a wide spectrum of Vascular and the whole range of MSK scans. Additionally, Sonoworld Diagnostics provides innovative well-being screening packages which can detect early some of the most common illnesses and can prevent life-threatening conditions.
