To prospectively compare computed tomography CT , magnetic resonance MR imaging, and bone scintigraphy in athletes with clinically suspected early stress injury of tibia. Sensitivity, specificity, and positive and negative predictive values of CT-CA vs. CT and MRI may be useful to better evaluate the abnormalities shown by plain radiography. Sensitivity in detecting stones, strictures and congenital ureteropelvic junction obstructions was respectively Epub Apr 8 Anno: MR pyelography can rapidly and accurately depict the morphological features of dilated urinary tracts with information regarding the degree and level of obstruction, without using contrast medium or ionizing radiation.
Perineural spread along the vidian nerve is an event more frequent than previously reported and must be investigated with a careful imaging technique. Significant difference in detection of early tibial stress injuries was found between MR imaging and both CT and bone scintigraphy McNemar test; P Combined magnetic resonance urography and targeted helical CT in patients with renal colic: Our purpose is to describe the imaging features in athletes with chronic lower leg pain, emphasizing the role of MRI and CT, which are the diagnostic tools with the highest sensitivity and specificity in the differential diagnosis of lower leg pain. Estimated average dose calculated from phantom study was 0. All of the subjects were informed about the study procedure. CT images from the 5 cm below the level of ureteral obstruction as demonstrated by MRU were selected out.
CT and MR imaging findings in athletes eurkpeo early tibial stress injuries: For CT a enlargement of the pterygoid canal, b erosion of its bony wall, and c obliteration of its normal fatty content; and for MR a enlargement of the vidian nerve, b enhancement of the nerve, and c obliteration of fat, particularly in the anterior part of the pterygoid canal.
The CT scans demonstrated unilateral involvement of the vidian nerve in 9 patients. McNemar test was used to detect statistically significant differences.
Plain radiography has a low sensitivity but may reveal tibial stress fractures, bone tumors, and soft-tissue calcification.
The aims of this article are to describe the findings of perividian tumor spread and to compare the accuracy of MRI and CT in diagnosing perineural metastasis along the vidian nerve. Location of stress injuries, types of bone alterations, and presence of periosteal and bone marrow edema were evaluated.
To evaluate the accuracy of MR pyelography in the assessment of hydroureteronephrosis.
The two protocols were compared regarding the following points: In 3 patients MR scans demonstrated involvement of four vidian nerves that appeared normal on CT examinations.
Sensitivity, specificity, tecnifo, and positive and negative predictive values of MR imaging and CT were assessed, as was sensitivity of bone scintigraphy.
All of the subjects were informed about the study procedure. Diagnostic accuracy of computed tomography coronary angiography in patients with a zero calcium score.
MR imaging, CT, and bone scintigraphy were performed in all patients within 1 month of onset of symptoms. CT images from the 5 cm below the level of ureteral obstruction as demonstrated by MRU were selected out.
Eight patients had bilateral involvement; thus, 50 tibiae were evaluated.
We used magnetic resonance MR pyelography to compare the value of thick-slab single-shot rapid acquisition with relaxation enhancement RARE sequence with that of multislice half-Fourier acquisition single-shot turbo-spin-echo HASTE sequence in evaluating the full spectrum of morphologic features in a group of patients with hydronephrosis.
Epub Apr 8 Anno: One hundred and fifteen patients, with variable degree of hydroureteronephrosis demonstrated by US and urography were subjected to MR pyelography obtained by means of two ultra-fast sequences. Moreover, the frequency of perividian metastasis in patients with head and neck cancer was evaluated.
At the maximal open-mouth position, the distance between the TMJ disk and the mandibular nerve is shorter in patients with TMJ-D and neuropathic pain than in patients with TMJ-D without neuropathic pain or in healthy volunteers P Diagnostic accuracy of computed tomography coronary angiography in patients with a zero calcium score.
Medical ethics committee approval and informed consent were obtained.
Sensitivity in detecting stones, strictures and congenital ureteropelvic junction obstructions was respectively Temporomandibular joint disorders TMJ-D may be associated with the onset of neuropathic pain. To prospectively compare computed tomography CTmagnetic resonance MR imaging, and bone scintigraphy in athletes with clinically suspected early stress injury of tibia. Although a major limitation of our study is the lack of histological proof, the MR finding of a significant enhancement of the nerve, vtae enlarged or normal in size, could be considered very suggestive of this kind of metastatic spreading, particularly if associated with simultaneous involvement of the neighboring structures pterygopalatine fossa, foramen lacerum, trigeminal branches, etc.
MR pyelography in the assessment of hydroureteronephrosis: We evaluated the distance between the TMJ disk and the mandibular nerve at the oval foramen level. Ten patients met the selected criteria for perineural metastasis, which was bilateral in 3 patients, with a total of 13 vidian metastases.
Furthermore, the presence within the TMJs of internal derangement, osteoarthrosis, joint effusion, and bone marrow edema was evaluated. The MRI scans showed 13 perineural metastases. CT and MRI may be useful radiologiq better evaluate the abnormalities shown by plain radiography. Protocol B consisted of the entire unenhanced helical CT of the urinary tract.
Our purpose is to describe the imaging features in athletes with chronic lower leg pain, emphasizing the role of MRI and CT, which are the diagnostic tools with the highest sensitivity and specificity in the differential hecnico of lower leg pain. Therefore, the effective radiation dose was 5.
All patients underwent initial radiography that was negative for injury. Estimated average dose calculated from phantom study was 0.
