Comparison of spin echo T1-weighted and FLASH 90 degrees gadolinium-enhanced magnetic resonance imaging in the detection of cerebral metastases.

The British journal of radiology

Cherryman G, Golfieri R.
PMID: 2400896
Br J Radiol. 1990 Sep;63(753):712-5. doi: 10.1259/0007-1285-63-753-712.

A direct comparison of post-gadolinium FLASH 90 degrees magnetic resonance (MR) images against conventional post-gadolinium T1-weighted spin echo MR images obtained in patients with suspected cerebral metastatic disease shows the FLASH sequence to be inferior. False negative FLASH 90...

Multiexponential proton spin-spin relaxation in MR imaging of human brain tumors.

Journal of computer assisted tomography

Schad LR, Brix G, Zuna I, Härle W, Lorenz WJ, Semmler W.
PMID: 2545751
J Comput Assist Tomogr. 1989 Jul-Aug;13(4):577-87. doi: 10.1097/00004728-198907000-00005.

In vivo measurements of proton relaxation processes in human brain tumors have been performed by magnetic resonance (MR) imaging using a whole-body superconductive MR scanner, operating at 1.5 T. The T1 and T2 relaxation time measurements were based on...

Theory of paramagnetic contrast agents in liposome systems.

Magnetic resonance in medicine

Barsky D, Pütz B, Schulten K, Magin RL.
PMID: 1313522
Magn Reson Med. 1992 Mar;24(1):1-13. doi: 10.1002/mrm.1910240102.

We develop a theoretical description of nuclear spin relaxation mediated by MRI contrast agents and transport processes in liposome systems. Such systems compartmentalize the physical space such that paramagnetic contrast agents, which enhance relaxation, are trapped in some subvolume....

[Differential diagnosis of cervical space occupying lesion: the parapharyngeal rhabdomyoma].

Laryngo- rhino- otologie

Ihrler S, Grevers G, Vogl T.
PMID: 1463564
Laryngorhinootologie. 1992 Nov;71(11):564-7. doi: 10.1055/s-2007-997356.

A case of a parapharyngeal rhabdomyoma is presented. Only about 30 cases of this benign tumor of striated muscles are reported in the literature. Most tumors were located in the lateral cervical region. Histologically a rhabdomyoma must be distinguished...

Fatty-acyl iminopolycarboxylates: lipophilic bifunctional contrast agents for NMR imaging.

Magnetic resonance in medicine

Kim SK, Pohost GM, Elgavish GA.
PMID: 1798395
Magn Reson Med. 1991 Nov;22(1):57-67. doi: 10.1002/mrm.1910220107.

New fatty-acyl contrast agents, N3-2'-myristoyloxyethyl-N6-2'-hydroxyethyl-1, 8-dioxotriethylenetetraamine-N,N,N',N'-tetraacetic acid (MHE-DTTA) and N3,N6-bis(2'-myristoyloxyethyl)-1,8-dioxo- triethylenetetraamine-N,N,N',N'-tetraacetic acid (BME-DTTA) were prepared by sequential alkylation, acylation, and catalytic hydrogenation from bis(hydroxyethyl)-ethylenediamine with satisfactory yields (overall 36-46%). The 1:1 gadolinium complexes of the ligands MHE-DTTA and BME-DTTA...

Comparative evaluation of two membrane-based liposomal MRI contrast agents.

Magnetic resonance in medicine

Karlik S, Florio E, Grant CW.
PMID: 2046538
Magn Reson Med. 1991 May;19(1):56-66. doi: 10.1002/mrm.1910190106.

Two phospholipids--one bearing a nitroxide free radical covalently attached to its polar headgroup, and the other bearing a similarly attached chelating agent with bound gadolinium--were compared in vivo as liposomal contrast agents for MR imaging. In each case the...

[Malignant chest wall infiltration in MR: comparison with CT and surgical findings].

RoFo : Fortschritte auf dem Gebiete der Rontgenstrahlen und der Nuklearmedizin

Bittner R, Schörner W, Sander B, Weiss T, Loddenkemper R, Kaiser D, Felix R.
PMID: 2554415
Rofo. 1989 Nov;151(5):590-6. doi: 10.1055/s-2008-1047247.

CT and MRI were performed on 19 patients with pleura related thoracic tumors with respect to the detection of chest-wall invasion. All patients underwent surgery, which confirmed malignant infiltration in 16 cases, while this was excluded in three. CT...

Perineural extension of nasopharyngeal carcinoma into the posterior cranial fossa detected by magnetic resonance imaging.

Clinical imaging

Mineura K, Kowada M, Tomura N.
PMID: 1933644
Clin Imaging. 1991 Jul-Sep;15(3):172-5. doi: 10.1016/0899-7071(91)90072-4.

We report a case with perineural extension of carcinoma arising from the nasopharynx. Magnetic resonance (MR) imaging with gadolinium-DTPA enhancement detected subtle but evident findings of perineural tumor extension through the jugulare foramen into the posterior cranial fossa.

Gadolinium-DTPA-enhanced magnetic resonance imaging of the isolated rat heart after ischemia and reperfusion.

Investigative radiology

de Roos A, Mohanlal RW, van Vaals JJ, Bergman AH, Doornbos J, Matheijssen NA, van der Wall EE, van der Laarse A.

The objective of this study was to assess the potential of gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) to identify myocardial ischemia and reperfusion in the isolated rat heart model. Ischemia was induced by reducing the perfusion pressure from 80 to 30...
