Web- Many of the disadvantages of digital radiography can be overcome by adequate training and having an understanding about how the system works - As mentioned previously as an advantage, digital radiography has a wider dynamic range but hits can also be seen as a disadvantage due to exposure creep. Heel Effect: A visual error related to X-ray production. CT examinations are about two and one-half times as expensive as sonographic examinations. Sonography can readily evaluate many common pediatric problems. Therapeutic enemas for constipation or intussusception reduction, Real-time evaluation of soft tissues (intra-abdominal organs) and vessels, No radiation exposure (D3+6D2+11D+6)y=0.

Dont be afraid to ask your doctor why a particular type of imaging test has been recommended. Most fluoroscopy is performed for gastrointestinal (GI) evaluation (barium swallowing, upper GI series, with or without a small bowel follow-through, barium enema) or genitourinary (GU) evaluation (cystograms and voiding urethrograms) (Figures 3 to 6). The object in the periphery appears smeared compared to the object at the center. (Image credit: shiobi/shutterstock) Basic Principles of Radiography .

Development and validation of a predictive model for stone-free failure after extracorporeal shockwave lithotripsy in patients with ureteral stone in a large prospective cohort. IV contrast material is not commonly required for imaging of the abdomen and pelvis as it is with most CT scans of these regions. Bone: Spongy bone appears light gray, while dense bone appears white. History: The need for radiography depends on the history of the individual. A differential diagnosis is based on radiologic findings, but also relies on relevant clinical and laboratory data. AJR 1995;164:1229, 5. Knowing the benefits and limitations of computed tomography, magnetic resonance imaging, and other techniques can help you request the right studies, prepare the family for the exam, and evaluate results. Initial stratification is based on age; American Urological Association (AUA) guidelines delineate patients <14 years old as paediatric patients. Graumann O, Osther SS, Spasojevic D, Osther PJ. It also increases the chances of intestinal perforation. ; Advantages Immediate image preview and availability Elimination of costly film processing steps A wider dynamic WebBenefits or advantages of digital radiography. In children, IV contrast media most often are used in CT. It is easy to perform and can be done on uncooperative patients, and, if correctly carried out and carefully interpreted, it can still be used with a dual purpose. They can occur for many reasons. A plain abdominal radiograph is a low-cost procedure that is easy to perform with inexpensive radiographic equipment. Small bowel has valvulae conniventes that traverse the full width of the bowel; large bowel has haustra that cross only part of the bowel wall. Suspected hepatobiliary disease and abdominal or pelvic processes are also indications for sonographic examinations (Figure 9). J Nuc Med 1996;37:185, 11. X-ray is one of the modern imaging techniques including ultrasound, CT scan and MRI A proposed algorithm for imaging, Figure 1. Comparison of stone size estimates by B-mode ultrasonography and CT, Figure 4. Other minimally invasive procedures using fluoroscopy include therapeutic enemas in suspected meconium ileus, joint aspirations (often better achieved using sonographic guidance), hydrostatic or air reduction of intussusception, and removal of esophageal coins. Computed tomography (CT) consists of many low-dose X-rays taken in sequence by a rotating X-ray tube. Bacterial vaginosis during pregnancy may heighten risk of preterm birth, pregnancy loss.

The cystogram requires placement of a catheter within the bladder, which can be painful. In medical imaging, the moving sources are red blood cells. Small and large bowel also can be distinguished, most easily when dilated, by their different mucosal markings. Since the child is within the bore of the magnet and cannot be seen well, he or she must be monitored, using MRcompatible equipment, for oxygenation (pulse oximetry) and pulse rate, as well as respiratory excursion and rate. This is seen as a mixture of gray densities representing a gas/liquid/solid mixture.
