Abstarct: PURPOSE: The purpose of this study is to describe the characteristic MRI, CT, and F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) findings of Wolffian tumor.

Methods: We reviewed preoperative images in four surgical cases of Wolffian tumor. MRI was available for review in all cases with additional diffusion-weighted images (DWI) in three, and contrast-enhanced images in two.

Evaluation between the Usability and Physicochemical Property of Acyclovir Ointments.

A lot of prescription medicines have become switch over-the-counter (OTC) medicines. However, additives in brand-name drugs, generic drugs, and switch OTC drugs differ; therefore, the feelings associated with the use of these medicines vary for patients. The aim of this study was to compare the physicochemical properties and the feeling of use (assuming skin as an index of usability) of acyclovir (ACV) ointments.

Characterization of -Glucosidase Inhibitor/Cyclodextrin Complex Prepared by Freeze-Drying.

Miglitol (MT) is an -glucosidase inhibitor with a postmeal blood glucose level lowering effect that is used to treat type 2 diabetes. In addition, -cyclodextrin (CD) has been reported to inhibit increases in postmeal blood glucose. The aim of this study was to prepare a freeze-dried product (FD) composed of MT and CD or CD (molar ratio of MT/CD = 1/1, MT/CD = 1/1) and to evaluate the physicochemical properties and biological activity of the FD.

MRI Findings of Inverted Urothelial Papilloma of the Bladder.

Objective: The objective of this study was to characterize MRI findings of inverted urothelial papilloma of the bladder.

Materials And Methods: Data pertaining to 16 patients with 18 pathologically proven inverted urothelial papillomas of the bladder who had undergone MRI were retrospectively collected from seven institutions. The shape and surface characteristics of the tumors were evaluated using T2-weighted MR images.

The prevalence of falling and status of physical function among elderly individuals with locomotive and visual/hearing disorders.

In a super-aged society, the need for prevention of locomotor dysfunction is growing, and evidence for feasible preventive measures is thus required. This study aimed to examine the relationship between these disorders and the prevalence rates for falling and physical function status. Participants included 1182 community-dwelling elderly Japanese individuals aged 60 and older.

Endometrial polyps: MR imaging features.

The purpose of this study is to evaluate the diagnostic usefulness of magnetic resonance imaging (MRI) characteristics of endometrial polyps in order to differentiate them from other endometrial lesions. MRI was retrospectively reviewed in 40 patients with pathologically proven endometrial polyps. Special attention was paid to the sizes, shapes, margins, internal structures, signal intensities, and post-contrast enhancement patterns.

Production of a hybrid 16-membered macrolide antibiotic by genetic engineering of Micromonospora sp. TPMA0041.

Some polyketide-derived bioactive compounds contain sugars attached to the aglycone core, and these sugars often enhance or impart specific biological activity to the molecule. Mycinamicin II, a 16-member macrolide antibiotic produced by Micromonospora griseorubida A11725, contains a branched lactone and two different deoxyhexose sugars, D-desosamine and D-mycinose, at the C-5 and C-21 positions, respectively. We previously engineered an expression plasmid pSETmycinose containing the D-mycinose biosynthesis genes from M.

Sclerosing stromal tumor of the ovary with atypical magnetic resonance imaging findings in a middle-aged woman.

We encountered a case of atypical sclerosing stromal tumor of the ovary (SST) in a middle-aged woman. This 52-year-old woman presented with a 2-year history of abdominal distention. Magnetic resonance imaging (MRI) showed a large mass extending from the pelvis to the epigastrium.

[Intralobar sequestration in elderly patient; report of a case].

A 71-year-old woman who had been treated as bronchitis was diagnosed as intralobar sequestration by a computed tomography scan. She had 2 episodes of hemosputum in recent 30 years but the amounts were small and they spontaneously stopped in a day. She had an abnormal vessel from thoracic descending aorta of which diameter was 1 cm draining to the basal segment of the left lung.

Evaluation of crossing vessels in patients with ureteropelvic junction obstruction by means of helical CT.

Helical computed tomography (CT) was used to demonstrate the distribution of crossing vessels in patients with ureteropelvic junction (UPJ) obstruction for planning surgical management. Twenty patients with symptomatic UPJ obstruction were evaluated with dual-phase contrast material-enhanced helical CT. In addition to axial images, coronal, sagittal, and curved paracoronal images along the crossing vessels or the UPJ were obtained by means of multiplanar reconstruction.

MR appearance of adenomatoid tumor of the uterus.

Reports on the radiological findings of adenomatoid tumor of the uterus are rare, and preoperative diagnosis is very difficult. To our knowledge, there have been no reports concerning the MR findings of adenomatoid tumor of the uterus. We report two cases of uterine adenomatoid tumor that showed the characteristic features of leiomyoma on MR images.

Lobar decrease in 99mTc-GSA accumulation in hilar cholangiocarcinoma.

Unlabelled: Hilar cholangiocarcinoma can obstruct hepatic ducts and involve the portal veins. Both biliary stasis and decrease in portal venous flow are known to reduce 99mTc-diethylenetriamine pentaacetic acid-galactosyl human serum albumin (GSA) accumulation. The specific relationship between these pathological conditions due to hilar cholangiocarcinomas and 99mTc-GSA accumulation has never been clarified.

Struma ovarii: appearance on MR images.

Background: The purpose of this multi-institutional study was to examine the appearance of struma ovarii on magnetic resonance (MR) images.

Methods: MR images of 12 patients with histologically proven struma ovarii were retrospectively reviewed. All patients underwent T1-weighted and T2-weighted imaging.

Preoperative evaluation of hepatic functional reserve following hepatectomy by technetium-99m galactosyl human serum albumin liver scintigraphy and computed tomography.

It is extremely important to have a good grasp of the acceptable limit of hepatectomy before operation because postoperative liver failure can take a fatal course; however, baseline data on the limit of hepatectomy have not been clearly defined. We therefore evaluated and compared the predicted remnant liver function obtained by computed tomography(CT) and technetium-99m diethylenetriamine penta-acetic acid-galactosyl human serum albumin (99mTc-GSA) liver scintigraphy in order to obtain precise data regarding remnant liver function before hepatectomy. We investigated 20 patients undergoing hepatectomy using the clearance rate of indocyanine green (KICG) as a parameter, and compared the predicted postoperative KICG obtained by CT and by transaxial single-photon emission tomographic (SPET) images acquired by 99mTc GSA liver scintigraphy before hepatectomy.

[Evaluation of the cystic duct and cysticohepatic junction with MR cholangiography: comparison of various techniques and clinical evaluation with respiratory-triggered three-dimensional multislab technique].

The purpose of this study was to evaluate depiction of the cystic duct and cysticohepatic junction by MR cholangiography (MRC). In 10 volunteers, MR cholangiograms were obtained by breath-hold two-dimensional (2D), respiratory-triggered 2D, respiratory-triggered three-dimensional (3D) single slab, and 3D multislab techniques. The images then were compared qualitatively.

Technetium-99m-DTPA-galactosyl human serum albumin liver scintigraphy evaluation of regional CT/MRI attenuation/signal intensity differences.

Unlabelled: Regional attenuation/signal intensity differences seen on CT/magnetic resonance imaging can be a clue in detecting regional hepatic blood flow abnormality. Sometimes, however, they can be misinterpreted as a hepatic neoplasm or, in the case of a true neoplasm, they can lead to an overestimation of its size because these regions often have similar attenuation or signal intensity to hepatic neoplasms. We evaluated 99mTc-diethylenetriaminepentaacetic acid-galactosyl human serum albumin (99mTc-DTPA-GSA) liver scintigrams in patients manifesting regional attenuation/signal intensity differences to further analyze the findings.

Cervical carcinoma: dynamic MR imaging with a turbo-FLASH technique.

The purpose of this study was to evaluate the characteristic findings of cervical carcinoma in dynamic MR imaging with a turbo-FLASH technique and to investigate the cause of the hyperintense rim surrounding the tumor on dynamic MR images by comparing them with the pathological findings in the resected specimens. Sixty consecutive patients with cervical carcinoma were included in this study. Dynamic MR imaging was performed with the rapid administration of Gd-DTPA using the turbo-FLASH technique.

I-123 uptake in nonfunctional struma ovarii.

A case of nonfunctional struma ovarii preoperatively diagnosed by scintigraphy of the pelvis using I-123 NaI is reported. US, CT, and MRI revealed a multilobulated mass composed of cystic and solid components. CT showed cystic components with slightly high density and MRI showed various signal intensities on T1- and T2-weighted images.

[Preoperative evaluation for volume reduction surgery of pulmonary emphysema using MRI: usefulness of HASTE (half-Fourier single-shot turbo SE) sequence during deep respiration].

Volume reduction surgery has recently been an important surgical procedure for patients with severe pulmonary emphysema. We compared the sagittal and coronal images taken by the HASTE sequence with those obtained by turbo FLASH during deep breathing and with CT images obtained under deep inspiration. Clear images were obtained from both sequences, without cardiac or respiratory motion artifacts.

Reduced radioactivity in the periphery of the liver in a patient with idiopathic portal hypertension.

The authors report a case of idiopathic portal hypertension in which radioaccumulation in the peripheral region of the liver decreased markedly. On dynamic CT, peripheral regional enhancement of the liver was seen in the arterial phase. The region was hypointense on T1-weighted MR images and hyperintense on T2-weighted images.

[Dynamic MR and fat suppression imaging of pancreatic carcinoma].

The usefulness of dynamic MR and fat suppression imaging was investigated in 19 patients with pancreatic duct cell carcinoma. In addition to conventional spin echo imaging, dynamic MR and fat suppression imaging were performed. These images were evaluated for the detectability of lesions.

Uterine cirsoid aneurysm: MRI and MRA.

Uterine cirsoid aneurysm is uncommon. It is important to make a diagnosis of this disease preoperatively, because repeated curettages may induce life-threatening massive genital bleeding. We present a case of a 51-year-old woman with uterine cirsoid aneurysm in whom MRI and MRA were very useful for the preoperative diagnosis.
