Disease relevance of Radiography

• On admission, patients with HPS were less likely than outpatients with influenza to have reported sore throat (OR = 0.02, P < .01) and cough (OR = 0.1, P = .01) and were less likely than patients with pneumococcal pneumonia to have lobar infiltrates detected by chest roentgenography (OR = 0, P < .01) [1].
• Increased serum prolactin (hPRL) and increased volume of the sella turcica as detected by roentgenography are compatible with a pituitary adenoma [2].
• The effect of joint exposure to diagnostic X-rays and maternal smoking during pregnancy was compared in a case-control study of 216 children with cancer (128 cases with acute lymphoblastic leukemia [ALL] and 88 with solid tumors) and 301 control children with insulin-dependent diabetes mellitus (IDDM) [3].
• Cervical roentgenography and magnetic resonance imaging revealed spondylitis of C5 and C6 [4].
• Not that the actual incidence of Congenital Lobar Emphysema has changed materially but increased clinical awareness of the possibility of the diagnosis and the widespread use of roentgenography in infants has clearly resulted in frequent recognition of this condition [5].

High impact information on Radiography

• In vivo assessment of the system included (1) dye contrast roentgenography, (2) vasopressin stimulation, and (3) reservoir volume monitoring [6].
• CONCLUSION: These data indicate that the risk of thyroid cancer due to medical diagnostic x rays, if any, is very small [7].
• The relative risk of thyroid cancer was not significantly associated with estimated cumulative dose to the thyroid gland from diagnostic x rays (two-sided P for trend = .80) [7].
• Endocrine evaluation included bone age roentgenography and measurement of growth hormone (using sequential arginine and insulin stimulation), thyroxine, thyroid-stimulating hormone, plasma cortisol, testosterone, prolactin, and urinary follicle-stimulating hormone and luteinizing hormone [8].
• The spectra of diagnostic x-ray beams were measured with a germanium semiconductor dectector [9].

Biological context of Radiography

• The patients with abnormal renal function received an additional 300 to 500 ml of intravenous fluid, plus 20 to 40 mg intravenous furosemide, 1 hour before roentgenography to establish a diuresis [10].
• Bone formation of fractured fibulae stimulated by pulsed electromagnetic fields (PEMF), PGE2, and combination of both was assessed with roentgenography and fluorescent labelling compounds, tetracycline, xylenol orange, and calcein [11].

Anatomical context of Radiography

• Described is a case of a thymoma which mimicked partial absence of the left pericardium on routine roentgenography [12].
• Plain roentgenography revealed a radiopaque mass with serpiginous density in the pelvic region [13].
• At intervals of 0.5 to 2 hr, roentgenography was conducted to identify the position of the barium sulfate in the digestive tract [14].

Associations of Radiography with chemical compounds

• CONCLUSIONS: At least 4 patterns of calcium oxalate stones are recognizable by plain film roentgenography [15].
• By matching of the attenuation and hardening properties, comparisons are made between shielding afforded by breast tissue materials (water, Lucite and 50%-50% adipose-glandular tissue) and some materials considered for shielding diagnostic x-ray beams, namely lead, steel and gypsum wallboard [16].
• Isotonic or low-osmolar nonionic roentgenography contrast media or gadopentetate did not show this effect or showed it only to a minimal extent [17].
• A simple way to place the risk associated with Nuclear Medicine studies in an appropriate context is to compare the dose with that received from a more familiar source of exposure such as from a diagnostic X-ray procedure [18].
• Serial chest roentgenography, pulmonary function studies, and the serum angiotensin-converting enzyme level are useful for monitoring the course of the disease [19].

Gene context of Radiography

• Such cysts may manifest as a symptomatic mass, as an asymptomatic finding on roentgenography, or during the assessment of a patient with hyperparathyroidism [20].
• With a new technique of roentgenography to reveal more accurately the degree of ulnar drift and radial deviation in hands of patients with rheumatoid arthritis, it was shown that the radial deviation was less marked than would be ascertained with conventional roentgenograms [21].
• RESULTS: In rabbit models, roentgenography showed that disc spaces treated with cathepsin L and chymopapain had become narrower 1 week after injection [22].
• The response to chemotherapy was grouped as specified as complete (CR), partial response (PR), no change (NC), and progressive disease (PD), according to the change in tumor size on chest roentgenography and CT [23].
• Quality assurance protocols for diagnostic x-ray equipment. Part 1: General radiographic units [24].

Analytical, diagnostic and therapeutic context of Radiography

• Comparison of documented and recalled histories of exposure to diagnostic x-rays in case-control studies of thyroid cancer [25].
• Results of roentgenography of the chest and echocardiography were consistent with a diagnosis of hypoplasia of the inferior vena cava with azygos continuation [26].
• At 14 and 28 days after operation the bone forming process was evaluated by roentgenography, planimetry included, and scintigraphy after injection of 99Tcm-labelled DPD [27].
• This took the form of detailed inspections of some 62 medical radiation departments, including Diagnostic X-ray, Radiotherapy, Nuclear Medicine and Pathology/Research (Radionuclide) Departments [28].
• METHODS: The analyzed clinical data from 78 patients with TS included those from detailed history, physical and dermatological examination, cranial computed tomography (CT) and magnetic resonance imaging (MRI), abdominal ultrasonography, chest roentgenography, hand and foot X-ray and ophthalmologic examination [29].
