PURPOSE: To (a) determine the performance of screening mammography, ultrasonography (US), and physical examination (PE); (b) analyze influence age, hormonal status, breast density; (c) compare size stage tumors detected with each modality; (d) which modality or combination modalities optimize cancer detection. MATERIALS AND METHODS: A total 11,130 asymptomatic women underwent 27,825 sessions, (mammography subsequent PE). Women dense breasts subsequently US. Abnormalities were deemed positive...
PURPOSE: To evaluate bilateral screening ultrasound (US) in the detection of otherwise occult masses and cancer women with dense breasts normal mammographic physical examination findings. MATERIALS AND METHODS: Of 11,220 consecutive patients prospectively examined, all 3,626 findings underwent physician-performed US. The size stage cancers detected US alone were compared those on mammograms, at examination, or both, remainder patients. RESULTS: In group women, 11 surgically proved...
Most studies of contrast-induced nephropathy lack controls to distinguish it from other causes. We assessed the frequency and magnitude serum creatinine changes in patients not receiving iodinated contrast material compare with publications regarding nephropathy.From electronic medical records an academic center, adults determinations on five consecutive days who had received during previous 10 were identified. The first level was compared those subsequent days. calculated which these levels...
Recurrent renal stones associated with urinary infection were treated in eight kidneys six patients by percutaneous nephrostomy and irrigation hemiacidrin, a commercially available solution of organic acids magnesium. The stones, presumably composed triple phosphates (magnesium, ammonium calcium phosphate), completely dissolved kidneys; two they partially subsequently recovered other methods. No serious complications encountered. technic requires special precautions against perinephric...
Abstract Magnetic resonance imaging was used to determine the T 2 relaxation times of prepared proteoglycan solutions and normal human intervertebral disc tissue from annulus fibrosus (AF) nucleus pulposus (NP). The collagen, proteoglycan, water contents samples were determined by biochemical assays after they scanned. Correlations among 1/ , water, calculated. A moderate negative correlation between content noted for samples, a very high found solutions. positive is probably due this...
Intravenous (IV) contrast medium is sometimes withheld due to risk of complication or lack availability in patients undergoing computed tomography (CT) for abdominal pain. The from withholding understudied.
Background Contrast nephropathy risk is traditionally assessed by the proportion of patients whose post-contrast serum creatinine (SCr) increases exceed certain thresholds. However, this method can be misleading because random threshold selections, overlooking decreases, and discarding continuous renal function data. The main impact contrast on revealed analyzing mean changes in SCr evaluating their significance. Purpose To analyze published data permitting calculation after intravenous...
PURPOSE: To correlate the radiologic and pathologic findings differential diagnosis of large, degenerated adrenal adenomas. MATERIALS AND METHODS: The authors reviewed characteristics 30 large adenomas with cystic regions or areas heterogeneity that were either intrinsic demonstrated at contrast material–enhanced computed tomography (CT) magnetic resonance (MR) imaging. Images 24 adrenocortical carcinomas also to determine whether differentiating existed. RESULTS: Most in asymptomatic women....
A series of 70 pyonephrotic kidneys drained by percutaneous nephrostomy tube was examined to evaluate the contribution radiologic imaging diagnosis pyonephrosis and assess diagnostic therapeutic role drainage catheter. The is suspected when clinical symptoms fever flank pain are combined with evidence obstruction urinary tract. Sonography gives a prompt hydronephrosis, needle puncture kidney yields pus establishes presence pyonephrosis. catheter then inserted serves for initial infected...
Small renal masses (SRM) can be managed via a variety of nephron-sparing procedures (NSPs), but the association between choice NSP and parenchymal volume (RPV) preservation is not well understood. We sought to examine RPV after partial nephrectomy (PN) performed open, robotic, or laparoscopic approaches thermal ablation (TA) cryoablation (CA) radiofrequency (RFA).The study was retrospective review three institutional databases patients with SRM <4 cm treated one five NSPs (open PN, robotic...

The distribution of 125I iothalamate between the intravascular and extravascular fluid compartments was determined after intravenous injection in dogs. Simultaneous measurements total blood volume, concentrations urinary excretion were made permitted calculation iothalamate. drug diffused very rapidly to space: more than half had reached space one minute injection. ratio rose a plateau 6.8. We conclude that contrast material responsible for tissue opacification during radiography is...
Fifty patients undergoing cranial CT had expanded-high-iodine-dose (EHID) scans. The EHID was given either as an additional bolus dose (37--40 g iodine) after a routine infusion contrast scan (42.3 g), or continuous (total 74--80 g). Diseases presented include primary and metastatic neoplasm, pituitary demyelinating disease. results suggest that the usefulness of is in (a) detecting multiple rather than solitary brain lesions, (b) definitive demonstration equivocal area abnormal enhancement,...
Study Type – Diagnosis (exploratory cohort) Level of Evidence 2b What’s known on the subject? and What does study add? For over 30 years it has been recognized that there is an association between end‐stage renal disease (ESRD) development malignancy, particularly cortical tumour. Observational studies have consistently shown patients with severely decreased glomerular filtration rate (GFR) develop cancer more frequently than their age‐ exposure‐matched controls. This first its kind to look...
